Named colors

工具介绍

Pick any color visually with a saturation/brightness canvas, hue slider, opacity slider, browser eyedropper, and image pixel sampler. Copy values in HEX, RGB, RGBA, HSL, or CMYK — or search the full CSS named-color library by name or hex.

工具概览

Most pickers stop at HEX and RGB. This one adds opacity (rgba and #RRGGBBAA), print-ready CMYK, desktop/screen sampling in supported browsers, and click-to-pick color extraction from image uploads or image URLs. A nearest-match label tells you the closest CSS named color for readability and handoff. Saved swatches live in memory only — nothing is uploaded.

使用场景

  • Use Color Picker when you need fast interactive color picker with eyedropper support, image upload and url sampling, saturation/brightness canvas, hue and opacity sliders, hex / rgb / rgba / hsl / cmyk output, css named-color lookup, nearest-name matching, and saved swatches.
  • Handle design workflows directly in the browser with no install required.
  • Support SEO long-tail intent by covering quick checks, troubleshooting, and one-off conversions.

常见问题

What is the hex code for red, blue, green, and yellow?+
Red is #ff0000 (rgb 255,0,0), green is #008000 (rgb 0,128,0) — pure green in CSS is called "lime" #00ff00 — blue is #0000ff (rgb 0,0,255), and yellow is #ffff00 (rgb 255,255,0).
What are the hex codes for orange, purple, pink, and brown?+
Orange is #ffa500, purple is #800080, pink is #ffc0cb, and brown is #a52a2a. CSS also has named variants like darkorange (#ff8c00), hotpink (#ff69b4), and saddlebrown (#8b4513).
What are the hex codes for black, white, gray, and silver?+
Black is #000000, white is #ffffff, gray is #808080, and silver is #c0c0c0. Off-whites like whitesmoke (#f5f5f5) and ghostwhite (#f8f8ff) are useful for softer backgrounds.
What is the hex for teal, cyan, navy, and indigo?+
Teal is #008080, cyan/aqua is #00ffff, navy is #000080, and indigo is #4b0082. Royal blue (#4169e1) and dodgerblue (#1e90ff) are popular mid-blues.
What is CMYK and when should I use it?+
CMYK (cyan, magenta, yellow, key/black) is the subtractive model used by printers. Web and screens use RGB. If you are exporting for print — flyers, business cards, packaging — convert your RGB value to CMYK so the printer gets predictable ink mixing.
What does the #RRGGBBAA hex format mean?+
The last two hex digits encode alpha from 00 (fully transparent) to ff (fully opaque). For example, #ff000080 is 50%-opaque red. Modern browsers accept it in CSS directly.
How is the "closest named color" found?+
The tool computes Euclidean distance in RGB space between your color and every CSS named color, then returns the nearest one. It is a quick approximation — perceptual distance (CIEDE2000) is more accurate but overkill for most labeling.
Can I pick a color from an image URL?+
Yes. Paste an image URL and click Load URL, then click any pixel on the preview to sample that exact color. Some hosts block cross-origin image access; in that case, upload the file directly.
Can I sample color from my desktop screen?+
Yes on supported browsers via the EyeDropper API. Click Pick from screen and choose any pixel. If your browser does not support EyeDropper, use image upload/URL sampling instead.
