The Color Analysis Encyclopedia
Every color analysis term from A to Z, each with a short definition and a link to the page that explains it. Below the terms are the topics, and every guide on the site.
The four traits
Every color analysis looks at the same four things. Each season is a mix of them.
Color analysis terms, A to Z
73 terms
#
- 4-season system
- The original Spring, Summer, Autumn and Winter. Books from 1978 and 1980 made it popular.
- 12-season system
- The system most analysts use today: the four seasons, each split three ways by the trait that leads (light, true, bright, soft or deep).
- 16-season system
- A system with 16 types. Its extra names, such as Soft Winter, sit between two of the 12 seasons.
A
- Analogous colors
- Colors next to each other on the color wheel, such as teal, blue and violet. An outfit of analogous colors looks calm.
- Ash
- A cool hair tone with no gold or red in it. Ash shades suit the cool seasons.
- Auburn
- Red-brown hair, from light copper auburn to dark chestnut auburn.
- Autumn
- The warm, soft-to-deep season family: Soft Autumn, True Autumn and Deep Autumn.
B
- Beige skin tone
- A light-to-medium skin tone with a yellow or neutral cast.
- Bright
- High chroma. A bright season wears clear, saturated colors: Bright Spring and Bright Winter. Also called "clear".
- Bright or muted
- The two ends of chroma. A bright coloring is clear and vivid, and a muted (soft) coloring is gentle and blended. Most people sit between.
C
- Chroma
- How bright or soft a color is. One of the four traits: in a person, how clear and vivid the coloring is. Munsell named it in 1905.
- Chroma axis
- The bright to soft score in our analysis, from -1 to +1. When the hair is readable, 70% is the hair to skin lightness gap and 30% is skin chroma.
- CIEDE2000
- The standard formula for how different two colors look. We use it to find the palette color nearest to any color.
- CIELAB
- A color space with three numbers: L* for lightness, a* for red to green, b* for yellow to blue. Our analysis measures skin in it.
- Clarity
- An older word for chroma in many color guides. Our report still labels the axis "Clarity".
- Clear
- Another name for bright. Clear Winter is Bright Winter, and Clear Spring is Bright Spring.
- Color analysis
- Finding the colors that suit your natural skin, hair and eyes. Also called personal color analysis.
- Color constancy
- How your eyes keep the color of an object about the same when the light changes. A camera does not do this, so a photo needs white balance.
- Color Me Beautiful
- Carole Jackson's 1980 book that took the four-season system to a mass market.
- Color temperature
- How warm or cool a light is, in kelvin. Indoor bulbs are warm, daylight is cooler. It changes how skin looks in a photo.
- Color theory
- The ideas that explain how colors look and work together: hue, value and chroma, warm and cool, and how a color changes next to another. Color analysis builds its four traits on them.
- Color wheel
- The hues in a circle. Opposite colors are complementary, neighbors are analogous.
- Colors to avoid
- The colors that work against a season. Each season page lists them, with the reason for each.
- Complementary colors
- Colors opposite each other on the color wheel, such as blue and orange. Together they make the strongest contrast of hue.
- Contrast
- One of the four traits: how far apart the lightness of your hair, skin and eyes is. High contrast is dark hair on light skin. Low contrast is hair, skin and eyes close in lightness.
- Cool undertone
- Skin with a pink, red or blue cast. Cool seasons are the Summers and the Winters.
D
- Deep
- Low lightness. A deep season wears dark, rich colors: Deep Autumn and Deep Winter. See depth
- Depth
- One of the four traits: how light or deep your coloring is overall. In color science it is value, or L* in CIELAB.
- Dominant trait
- The trait that defines a season most. For Soft Autumn it is chroma (soft), for Deep Winter it is depth (deep).
- Drape
- A piece of colored fabric held under the face. An analyst compares drapes in pairs to see which color suits the skin.
E
- Eumelanin and pheomelanin
- The two pigments of hair: black-brown eumelanin and red-brown pheomelanin. Their amount and ratio make most of the hair color.
F
- Fair skin
- Very light skin, in a cool, neutral or warm undertone.
- Family
- One of the four groups of seasons: Spring, Summer, Autumn or Winter. Each family holds three seasons.
- Fitzpatrick skin type
- A dermatology scale of six types by how skin reacts to the sun. It does not measure undertone.
G
- Gold or silver test
- A home test: which metal looks better against your skin. Gold often suits warm skin, silver cool skin. It is a hint, not a result.
H
- Hex code
- A six-character code for a screen color, such as #C65D3B. Every swatch on this site has one, so you can match it when you shop.
- Hue
- The name of a color: red, yellow, green, blue and so on. In Munsell terms, one of the three qualities of a color.
- Hue angle
- The position of a color on the color wheel, in degrees, worked out in CIELAB from the a* and b* numbers.
I
- Individual Typology Angle (ITA)
- An angle computed from L* and b* that sorts skin from very light to dark. Our skin tone chart and analysis use it for depth.
K
- Korean personal color
- The Korean form of seasonal analysis, with types such as spring light and winter deep.
L
- Light
- High lightness. A light season wears delicate, light colors: Light Spring and Light Summer. See depth
M
- Melanin
- The main pigment of skin, hair and eyes. With hemoglobin, bilirubin and carotene, it makes skin color.
- Metamerism
- When two colors match under one light and do not match under another. It is why a top can look different in the shop and in daylight.
- Monk Skin Tone Scale
- A 10-point skin tone scale, made to cover more skin tones than the Fitzpatrick scale.
- Munsell color chart
- A chart that arranges colors by hue, value and chroma. The one on our Munsell page plots each season palette by CIELAB lightness and chroma.
- Munsell color system
- A system from 1905 that describes every color by hue, value and chroma. Undertone, depth and chroma come from these three.
- Muted
- Low chroma: dusty, grayed colors. Another word for soft.
N
- Neutral undertone
- Skin that is neither clearly warm nor clearly cool. Neutral skin often sits between two seasons.
- Neutrals
- The base colors of a wardrobe: black, white, navy, gray, brown, beige. Each season has its own versions.
O
- Olive undertone
- Skin with a green or gray cast over a warm or neutral base.
P
- Palette
- The set of colors that suit a season, usually about 20 colors and a few neutrals.
- Peach skin tone
- Light skin with a warm pink-orange cast, between pink and golden.
R
- Runner-up season
- The second-closest season in a reading. Our report always shows it, and how close it came.
S
- Saturation
- The everyday word for how strong a color is. In color analysis the same idea is called chroma.
- Season
- One of the 12 types in seasonal color analysis, such as Soft Autumn. Each has its own palette.
- Seasonal color analysis
- Color analysis that sorts people into seasons by undertone, depth and chroma.
- Simultaneous contrast
- A color looks different next to different colors. Chevreul named it in 1839. Studies show it changes how skin tone looks, too.
- Simultaneous lightness contrast
- A patch looks lighter or darker depending on how light or dark its surroundings are. In one study it changed the rated skin tone of a face.
- Skin tone
- How light or dark the skin is. Undertone is a different thing: the cast under the surface.
- Soft
- Low chroma. A soft season wears muted, gentle colors: Soft Summer and Soft Autumn.
- Spring
- The warm, light-to-bright season family: Light Spring, True Spring and Bright Spring.
- Summer
- The cool, light-to-soft season family: Light Summer, True Summer and Soft Summer.
T
- Tonal color analysis
- A way to name a person by their strongest trait alone: deep, light, warm, cool, clear or soft.
- Triadic colors
- Three colors spread evenly round the color wheel, about 120 degrees apart.
- True
- The middle season of a family, led by its undertone: True Spring, True Summer, True Autumn, True Winter.
U
- Undertone
- One of the four traits: whether your skin leans warm (golden), cool (pink or blue) or neutral.
V
- Value
- How light or dark a color is, in Munsell terms. In color analysis it is called depth. See depth
- Vein test
- Checking if your wrist veins look blue or green. No study tests it, and vein color depends on more than undertone.
- Von Luschan scale
- An old skin tone scale of colored tiles matched by eye. A modern study compared it with instrument readings.
W
- Warm and cool colors
- Warm colors lean toward red, orange and yellow, and cool colors toward blue, violet and blue-green. Itten listed warm-cold among the named color contrasts, and where the line falls is a choice.
- Warm undertone
- Skin with a golden, yellow or peach cast. Warm seasons are the Springs and the Autumns.
- White balance
- Correcting a photo so white looks white. Our analysis uses the white of the eye to correct the light before it reads your skin.
- Winter
- The cool, deep-to-bright season family: Deep Winter, True Winter and Bright Winter.

Common claims the evidence does not support
- The vein test (blue veins = cool, green veins = warm) finds your undertone. (see S22)
- Each person fits exactly one of four (or twelve) seasons, defined by science. (see S33, S41, S45)
- Skin undertone decides which clothing colors suit you. (see S34, S33)
- Winter types have cool (low b*) skin, autumn types warm skin, in measured data. (see S41)
- Seasonal draping is a validated, repeatable test. (see S41, S42)
- Red clothing makes people more attractive. (see S31)
- Colors have reliable psychological effects (calming blue, energising red). (see S32)
- Fitzpatrick type tells you your skin tone or undertone. (see S13, S15)
- Contrast makes you look younger, healthier or better in clothes. (see S23, S24, S25)
- An app proves your season. (see S43, S44, S45)
What a definition cannot do
A definition tells you what a word means. It cannot tell you which season you are: that needs your own skin, hair and eyes in good light. Our free analysis reads them from one selfie, in your browser.
How this is different from other color analysis tools
- 01
Your photo stays on your device
Many photo apps upload your selfie and read it on their server (see our comparison). Ours measures it in your browser. There is no upload.
- 02
The result is free
Your season and palette, with no account and no email. At least one app in our comparison takes payment before you see any result.
- 03
A close call says so
Every result names the runner-up season and how close the call was. Borderline is a result we print.
- 04
We publish our accuracy
We tuned the method on faces that experts had labelled by season, then tested it on 410 celebrity photos we collected. The results, misses included.
What you can do on this page
This page is a glossary of color analysis: 73 terms from A to Z, each with a one- or two-sentence definition and a link to the page that explains it, and a box that filters the terms as you type. It groups the site's articles by topic (the four traits, skin, hair, the seasons, wearing your colors, our research). The free photo analysis reads undertone, depth and chroma from one selfie in the browser, with no upload and no account.
