Color converter

Model reference

Below are brief descriptions of the color models supported by this tool.

HEX

HEX is the hexadecimal form of RGB. #RRGGBB uses one byte per red, green and blue component. Short form #RGB is allowed where each character is doubled. Common in CSS/HTML and design specifications.

RGB / RGBA

RGB defines color as a mix of red, green and blue, 0–255 or in percent. RGBA adds alpha (opacity) from 0 to 1. Common on screens and the Web; used by CSS rgb()/rgba() and most digital graphics.

HSL / HSLA

HSL is a cylindrical representation of RGB: Hue (0–360°), Saturation (0–100%), Lightness (0–100%). HSLA adds an alpha channel. Useful for picking tints and lightness. Common in CSS color pickers and UI theming; supported by CSS hsl()/hsla().

HSB / HSV

HSB/HSV is similar to HSL but uses brightness/value instead of lightness. Widely used in graphics editors, color pickers and UI sliders in design tools.

CMYK

CMYK is a subtractive print model: higher values produce darker colors. Components are given as ink percentages for C, M, Y and K. Used for printing/press; common in prepress workflows and CMYK profiles.

XYZ

CIE 1931 XYZ is a reference color space with imaginary primaries; used as a base for technical color conversions. Used in color science and device‑independent workflows; not a format for everyday design or CSS.

LAB

CIELAB (1976) is computed from XYZ and is closer to human perception: equal coordinate changes yield similar visual differences. Used for color difference (ΔE), calibration/profiling and device‑independent processing.

What it is

The color converter translates between HEX, RGB/RGBA, HSL/HSLA, HSB/HSV, CMYK, XYZ and LAB. It is useful for UI design, hand‑off to print and basic color science tasks.

How it works

Type a color in any field — all other models update instantly. Use the Random button to generate a sample. RGB accepts 0–255 or percentages, HSV and HSB are interchangeable, and RGBA/HSLA include an alpha (opacity) value.

Limitations & notes

  • Calculations assume the sRGB color space with a D65 white point. XYZ/LAB are derived for D65.
  • Values are rounded (channels to integers, some outputs to 2 decimals), so round‑trips may differ slightly.
  • CMYK conversion here is a device‑independent approximation (no ICC profiles); press results may vary.
  • Alpha applies only to RGBA/HSLA. Other models are shown as opaque.
