Three Formats, One Color
HEX, RGB, and HSL are three different ways to describe the same color. A designer might work in HSL for intuitive palette building; a developer might copy HEX directly into CSS; a print workflow might need RGB component values separately.
Bidirectional Conversion
Edit any of the three color fields and the other two update instantly. The color preview swatch shows the exact color you are working with so you can verify visually before copying to code.

The Calculation Branch
Industrial Standards.
HEX to RGB is a straightforward base-16 to base-10 conversion per channel. RGB to HSL calculates the maximum and minimum channel values to determine lightness, then computes saturation and hue angle. All conversions are bidirectional.
In-Depth Analysis & Reference Data
In CSS, you can use any of these formats interchangeably: color: #3B82F6, color: rgb(59, 130, 246), or color: hsl(217, 91%, 60%). The modern oklch() and color() CSS functions offer wider gamut support but are best converted from HSL using dedicated tools. For Tailwind CSS users: Tailwind's blue-500 is #3B82F6 — try it above.
Registry Questions & FAQ.
How do I add opacity to a color?
In CSS, use the fourth channel: rgba(59, 130, 246, 0.5) for 50% opacity RGB, or hsla(217, 91%, 60%, 0.5) for HSL. Modern CSS also supports 8-digit HEX: #3B82F680 (the last two digits are the alpha channel in hex).
Why does RGB to HSL conversion lose precision?
Both conversions involve rounding. When you convert HEX → HSL → HEX, you may get a slightly different HEX value due to integer rounding in the H, S, and L fields. For exact round-trips, preserve the original format and only convert for display or export purposes.
