Key Takeaways

  • HEX and RGB are most common
  • CMYK is the color model for print
  • Alpha represents opacity — from 0 (transparent) to 1 (fully opaque)
  • 6-character HEX is #RRGGBB

What is Color Converter?

Color Converter translates any color between the five most-used color formats — HEX, RGB, HSL, HSB/HSV, and CMYK — instantly. Enter a color in any format and see all five representations at once.

Different workflows use different formats: design tools export HEX, CSS uses RGB or HSL, and print requires CMYK. Color Converter bridges all of them in one step.


The Five Color Formats

HEX

#RRGGBB — two hex digits per channel. Universal in web design, Figma tokens, and design handoff.

RGB

Red, Green, Blue from 0–255. The CSS rgb() function. Intuitive for screen color mixing.

HSL

Hue (0–360°), Saturation (%), Lightness (%). Best for generating color variations programmatically.

HSB

Hue, Saturation, Brightness. Used in Photoshop's color picker — similar to HSL but with different brightness model.


How to Use Color Converter

Enter your color

Type or paste a color value in any of the five format fields — HEX, RGB, HSL, HSB, or CMYK.

When to Use Each Format

FormatBest For
HEXFigma design tokens, HTML attributes, CSS variables
RGBCSS color values, canvas drawing APIs
HSLCSS theming, dynamically lightening/darkening colors
HSBPhotoshop color picker, creative tools
CMYKPrint design, PDF export, physical print production

Tips & Common Mistakes

HSL is the most powerful format for theming. You can create a full tint/shade scale by keeping the same Hue and Saturation and varying only Lightness.

CMYK conversions are approximations. RGB and CMYK have different color gamuts — some RGB colors (especially very saturated ones) cannot be perfectly reproduced in CMYK print. The conversion gives the closest printable equivalent.

Frequently Asked Questions

Which color format should I use in CSS?
HEX and RGB are most common. HSL is best for programmatic manipulation — you can adjust lightness with a single value without affecting hue.
When is CMYK used?
CMYK is the color model for print. Screens use RGB light; printers use CMYK ink. Always convert to CMYK before sending artwork to a printer.
What is the alpha channel?
Alpha represents opacity — from 0 (transparent) to 1 (fully opaque). It adds an 'A' to RGB and HSL: rgba() and hsla().
Why do HEX colors have 6 or 8 characters?
6-character HEX is #RRGGBB. 8-character HEX adds an alpha channel as the last two digits: #RRGGBBAA.
