What is the difference between RGB and HEX?

They represent the same colors differently. HEX uses base-16 notation (#FF5733), while RGB uses decimal values (255, 87, 51). Both describe red, green, blue channels from 0-255.

HSL stands for Hue, Saturation, Lightness. It's more intuitive than RGB — hue is the color (0-360°), saturation is vividness (0-100%), lightness is brightness (0-100%).

Conversion accuracy and color spaces

RGB, HEX, and HSL all operate in the sRGB color space and convert between each other with zero data loss — they are mathematically equivalent representations of the same color. CMYK conversion is an approximation: RGB colors have a wider gamut than CMYK (which is a subtractive ink model), so bright neons and saturated blues cannot be perfectly reproduced in CMYK. LAB (CIELAB) is a perceptually uniform color space — equal numerical distances correspond to equal perceived color differences, making it ideal for color interpolation and accessibility analysis.

Practical conversion scenarios

Designers often need to convert Figma HEX values to CSS hsl() for easier theming (HSL lightness is the cleanest axis to manipulate programmatically). Print designers need RGB-to-CMYK for offset printing where screen colors must be matched to ink. Brand guidelines frequently specify Pantone or CMYK values that front-end developers must translate to HEX. The LAB format is used in data visualization when constructing perceptually uniform color scales where every step looks equally spaced to the human eye.

Glossary

sRGB: The standard RGB color space for screens and the web — the default color space in CSS and HTML.
CMYK: Cyan-Magenta-Yellow-Key (Black) — a subtractive color model used in color printing.
CIELAB (LAB): A perceptually uniform color space where equal numerical differences correspond to equal perceived color changes.
Color gamut: The range of colors a device or color space can represent — sRGB is narrower than P3 or ProPhoto RGB.
