About Color Converter

Color Converter translates a single color across the formats designers and developers actually use: HEX (CSS, design tokens), RGB and RGBA (canvas, WebGL), HSL and HSV (color pickers and shader tweaking), and CMYK (print prepress). The tool applies the standard gamut math — gamma-corrected sRGB is the source of truth, with HSL/HSV computed as linear functions of the sRGB primaries and CMYK derived assuming a standard SWOP profile. Slight out-of-gamut shifts can happen when going CMYK→RGB (print-only colors like neon green map to the nearest reproducible sRGB). The page is static; type any color in any field and the others update instantly.

Best for

  • Web developers translating a brand HEX token into RGBA for canvas alpha tweaks
  • Designers pasting an HSL value from Figma into a CSS variable in HEX
  • Print preflight matching a screen color to a CMYK SWOP approximation

Pros

  • +HEX, RGB, RGBA, HSL, HSV, CMYK — all formats on one panel
  • +sRGB-correct gamut math; CMYK uses a standard SWOP profile assumption
  • +Single input updates every output instantly; nothing uploaded

Cons

  • −sRGB only — Display P3 and Adobe RGB wide-gamut conversions are not supported
  • −Spot colors (Pantone) live in the RAL/HKS tool, not here

Frequently Asked Questions

Why does my CMYK color look different on screen?
CMYK is a print model with a smaller gamut than sRGB; certain CMYK combinations (especially saturated greens and blues) have no exact RGB equivalent. The tool maps out-of-gamut CMYK to the nearest reproducible sRGB; the printed swatch in a Pantone book is the most accurate reference.
What's the difference between RGB and HSL?
RGB encodes raw red/green/blue intensity (0–255) for each channel. HSL puts hue on a 0–360° circle, with lightness and saturation as 0–100% — much easier for humans to tweak (e.g. 50° hue with 70% lightness = a warm pastel orange).
Are HEX and RGB the same thing?
For 8-bit color, yes — #FA3C2A is just (250, 60, 42) in red/green/blue. HEX is the compact single-string form used by CSS; RGB is the numeric form used by canvas, WebGL, and JavaScript color math.
Why is HSV different from HSL?
HSV keeps Value = max channel intensity regardless of lightness; HSL lightness = the midpoint of min and max channels. HSV is used by photo-editing color pickers; HSL is used in CSS variables and design systems. Both share the same hue angle convention.
Is my color input uploaded anywhere?
No. The conversion math is pure JavaScript embedded in the page; nothing you type leaves your device. Brand colors, design tokens, client swatches — all stay local.
