Other tools you may find usefulColor Name Generator - Identify and Name Each Hue HEX
Is #7C4DFF "Medium Slaty Violet" or "Light Lily"? The tool identifies each HEX color and matches it to the closest named color from the CSS Named Colors database, the X11 list, the Crayola dictionary and Polish color names. Useful for documenting color palettes.
Color name database sources
CSS Named Colors (148 names): official CSS names – aqua, coral, dodgerblue. X11 Color Names (752): extended list from the X Window system. Crayola (133): crayons – Razzmatazz, Tickle Me Pink. Pantone PMS: printing standards. Wikipedia Color List: Polish names in PL localization. "Xkcd Color Survey" (954): names given by 200,000 Internet users.
How base matching works
HEX to LAB (perceptually uniform) color space. Calculation of the distance ΔE (Delta-E) to each color in the database. Lowest ΔE = most similar name. ΔE < 1: virtually identical. ΔE 1-3: barely noticeable difference. ΔE > 10: clear difference.
Polish color names
Basic: red, blue, green, yellow, purple, orange, pink, brown, gray, white, black. Extended: magenta, scarlet, amaranth, burgundy, turquoise, emerald, cobalt, navy blue, olive, beige, sand, salmon, coral. Fashion and design: ecru, taupe, greige (gray-beige), mauve (dirty purple).
Professional uses
Documenting the design palette with clear names. Communication with the customer (instead of HEX - "dark bottle green"). Selection of paints (RAL, NCS) based on HEX. Export to Figma: Style Dictionary generates token names. Brand book: translating hex into human names.
FAQ
Why can the same color have multiple names?
No global standard for color names. Different cultures have different numbers of basic color categories (e.g. languages with 2-11 basic names). Crayola comes up with poetic names (Maroon 5 → "Brick Red"). CSS has defined 148 names historically - some are computer terms not used today (khaki, peru, bisque).
What is ΔE and how to interpret it?
ΔE (Delta-E) measures the perceptual difference between colors in LAB space. CIE76: simplest (only Euclidean distance in LAB). CIEDE2000: takes into account non-linearities of perception, more precise. ΔE < 2: practically indistinguishable colors. ΔE 2-10: visible difference but the same "type" of color.
How does color perception work in humans?
Retinal cones: L (red, ~560nm), M (green, ~530nm), S (blue, ~430nm). The signal is converted into channels: achromatic (brightness), red-green, yellow-blue. Hence, LAB/LCH spaces model perception through these channels. Color blindness: absence or dysfunction of one type of cones.
How do color names vary between cultures?
English has separate words for "blue" and "green". Russian has separate words for light blue (goluboy) and dark blue (siniy). The Japanese "aoi" meant both (green and blue) historically. Pirahã (Amazon): only 2 color categories (dark/light). Study: Regier & Kay 2009 – "Basic Color Terms".
How to create names for design tokens?
Convention 1: descriptive name (color-primary-500, color-neutral-200). Convention 2: contextual (color-button-background, color-text-muted). Convention 3: human name + number (cobalt-500). Style Dictionary (Amazon): Automatically generate token names from palettes. Figma Variables: the latest standard.
