Understanding Color Formats
HEX Codes
A 6-digit hexadecimal format (e.g. #FF5733). This is the standard for web development and graphic design inside tools like Figma.
RGB(A)
Red, Green, Blue. Commonly used in CSS when you need to apply an alpha channel (opacity) to a specific element's background.
HSL
Hue, Saturation, Lightness. The preferred format for programmatically building design systems, as it allows mathematical adjustments to lightness.
Tailwind CSS Palette Generation
If you are a front-end developer using utility-first frameworks like Tailwind CSS, you often need an entire color scale, not just a single primary color.
Our tool automatically extrapolates your selected base color into an 11-step scale (from 50 to 950). It adjusts the Lightness property (and mildly tweaks Saturation at extremes) to guarantee you have suitable combinations for background layers, active states, rings, borders, and text contrasts.
