Free color tools — convert between HEX, RGB, HSL, OKLCH and other color formats instantly.
QuickToolz Color Tools helps designers and developers convert between every common color format used on the web. Drop in a HEX, RGB, HSL, HSV, or OKLCH value and get all other formats back in real time — perfect for building design tokens, theming components, or matching brand colors.
HEX — #3b82f6 style web colors
RGB / RGBA — rgb(59, 130, 246) with optional alpha
HSL / HSLA — hue, saturation, lightness
HSV / HSB — used in many design tools (Figma, Photoshop)
OKLCH — the modern perceptually-uniform color space used by Tailwind v4
Different tools and contexts expect different color formats. CSS accepts them all, but design tokens, accessibility checks, and modern color spaces like OKLCH unlock better gradient interpolation, contrast control, and theme generation.
