RGB ↔ HEX Color Converter
Convert colors between RGB, HEX, and HSL formats instantly.
What Is the RGB ↔ HEX Color Converter?
The RGB/HEX Color Converter converts between RGB (Red, Green, Blue) values, hexadecimal color codes (#RRGGBB), HSL (Hue, Saturation, Lightness), and HSV/HSB color models. Enter any color representation to instantly see all equivalent values and a color preview.
Formula
How to Use
Enter a color in any format: HEX code (e.g., #FF5733), RGB values (e.g., 255, 87, 51), or HSL values. The converter displays all equivalent representations, a live color swatch preview, and the CSS color name if it matches a named color.
Example Calculation
#FF5733: R=255, G=87, B=51. = rgb(255, 87, 51). HSL: H=11°, S=100%, L=60%. HSV: H=11°, S=80%, V=100%. This is a vivid orange-red color. #000000=Black, #FFFFFF=White, #FF0000=Red.
Understanding RGB ↔ HEX Color Converter
Color representation in digital systems relies on the RGB color model, where any color is a combination of red, green, and blue light intensities. The RGB model is additive — combining all three at full intensity gives white. HEX codes are simply a compact hexadecimal notation for the same three channel values, used universally in web design CSS, HTML, and graphics software.
The HSL (Hue-Saturation-Lightness) model is more intuitive for color selection: hue is the color angle (0°=red, 120°=green, 240°=blue), saturation controls color purity (0%=grey, 100%=vivid), and lightness controls brightness (0%=black, 100%=white). Web designers often work in HSL because it makes systematic color variations (lighter/darker tones, less/more saturated versions) easy to compute.
Color conversion is needed in graphic design (between tools using different models), web development (CSS color values), image processing (color space transformations), print production (RGB to CMYK conversion for accurate print reproduction), and accessibility design (checking color contrast ratios for WCAG compliance). This converter handles all major color models with a live visual preview.
Frequently Asked Questions
What is the difference between RGB and HEX?
They represent the same color model — RGB using decimal numbers (0-255 per channel) and HEX using hexadecimal notation (00-FF per channel). #FF0000 is identical to rgb(255, 0, 0) — both specify pure red.
What does the # in hex colors mean?
The # symbol indicates a hexadecimal color code. The following six characters are three pairs of hex digits representing red (RR), green (GG), and blue (BB) channel intensities from 00 (none) to FF (full).
What is the difference between HSL and HSV?
Both use Hue (color angle), Saturation. HSL uses Lightness (0%=black, 50%=pure color, 100%=white). HSV uses Value (0%=black, 100%=full color brightness). HSL is more perceptually intuitive for web design; HSV is common in graphics editors.
What is RGBA?
RGBA adds an Alpha channel to RGB for transparency. Alpha ranges from 0 (fully transparent) to 255 (or 1.0 in CSS). Example: rgba(255, 0, 0, 0.5) is a semi-transparent red.
