Colour Picker — HEX, RGB, HSV, HSL, CMYK
Interactive colour picker that converts between every major colour format in real time.
這個工具是做什麼的
Pick a colour from the visual gradient or type values directly into any of the HEX, RGB, HSV, HSL, or CMYK rows. All other rows update instantly so you can move between formats without leaving the page.
Designed for designers, developers, and anyone matching colours across tools that use different colour spaces.
使用方法
- Drag the picker on the colour gradient, or click anywhere in the gradient to choose a base hue.
- Adjust the hue slider for fine control of the base colour.
- Edit any of the HEX / RGB / HSV / HSL / CMYK values directly — the others reconcile in real time.
- Click any row to copy the formatted colour value to your clipboard.
常見問題
Which colour formats are supported?
HEX (#rrggbb), RGB (red/green/blue 0–255), HSV (hue/saturation/value), HSL (hue/saturation/lightness), and CMYK (cyan/magenta/yellow/black 0–100%).
Does it handle alpha (transparency)?
The picker focuses on opaque colours; alpha is not part of the active workflow.
Are CMYK values device-accurate for print?
CMYK conversion uses the standard sRGB → CMYK formula. For colour-managed printing, always validate with your printer's ICC profile.
Can I copy a value with one click?
Yes. Clicking any of the format rows copies that representation to your clipboard.
