Digital color is expressed in multiple notations depending on the context: HEX triplets (#FF6B35) in CSS and HTML, RGB tuples in graphics APIs and CSS, HSL (hue, saturation, lightness) for programmatic color manipulation, and named CSS keywords (coral, rebeccapurple) defined in the CSS Color Level 4 specification. Each notation represents the same sRGB value differently.

Designers work in HEX when writing CSS, RGB when using canvas or WebGL APIs, and HSL when generating color palettes algorithmically (rotating hue while holding saturation and lightness constant). Figma exports HEX; CSS filter functions use HSL percentages; Android XML themes use #AARRGGBB hex with alpha. Conversion between these is a constant friction point.

This tool converts among HEX, RGB, HSL, and named CSS colors instantly, with a live color swatch that updates as you type so you can visually confirm the result. All math runs in the browser using standard sRGB conversion formulas with no external color library dependency.

Common Use Cases

Translating Figma exports to CSS variables

Figma's inspect panel outputs colors as HEX values. Design systems defined with CSS custom properties often store both HEX and HSL variants (--brand-primary: #7c6aff; --brand-primary-hsl: 250 100% 71%) so components can manipulate lightness in calc() expressions. Converting once here populates both variable values.

Generating accessible color palette variants

WCAG contrast ratio calculations work on relative luminance derived from linear RGB. When building accessible UI libraries, converting a brand HEX color to HSL lets you programmatically shift lightness (hsl(250, 80%, 30%) vs hsl(250, 80%, 70%)) to produce dark and light variants that maintain the hue identity.

Matching design tokens across platforms

iOS uses UIColor(red:green:blue:alpha:) with decimal RGB components (0.0–1.0), while web uses 0–255 integers. A designer delivering #3D9BE9 needs it expressed as rgb(61, 155, 233) for Android XML and as (0.239, 0.608, 0.914) for iOS Swift code. Converting via this tool covers all three at once.

Verifying color accuracy in print workflows

Print designers working with Pantone spot colors often receive HEX approximations for screen display. Converting a hex value to RGB here and checking it against the Pantone color bridge guide confirms whether the screen representation is within acceptable tolerance before sending files to a print service provider.
