Color Converters

Convert between every colour model designers and developers use — HEX, RGB, HSV, CMYK and Pantone — with live previews and exact values.

Every colour model, one place

Screens mix light in RGB and the web writes it as HEX; designers reason about colour in HSV; printers mix ink in CMYK; and brands lock their colours to the Pantone system for consistency. Moving a single colour between these worlds by hand is fiddly and error-prone — these converters do it instantly, with a live swatch so you can see the result.

Conversions between RGB, HEX and HSV are exact and reversible. Conversions involving CMYK and Pantone are necessarily approximate, because ink and spot colours can't perfectly reproduce every screen colour — each tool is upfront about that.

Exact vs. approximate conversions

  • RGB ↔ HEX ↔ HSV are lossless — they describe the same screen colour different ways, so you can round-trip freely.
  • RGB/HEX → CMYK is an approximation; print colour depends on paper, ink and profile, so treat it as a starting point.
  • → Pantone finds the nearest spot colour from a fixed palette of ~2,000 — verify critical brand colours against a physical Pantone book.
  • For digital work, stick to HEX/RGB/HSV. For print and branding, bring CMYK and Pantone into the conversation.

Frequently asked questions

RGB, HEX and HSV conversions are mathematically exact and fully reversible. CMYK and Pantone conversions are approximations, because those systems describe physical ink and can't reproduce every on-screen colour.

Screens emit light (additive) while print absorbs it (subtractive). Some vivid RGB colours simply fall outside the CMYK gamut, so the converter returns the closest printable equivalent.

Use it as a strong starting point. For critical brand colours, always confirm against a physical Pantone swatch book under proper lighting, since screens vary.

Both separate hue from saturation, but HSV (also called HSB) uses 'value' for brightness while HSL uses 'lightness'. These tools work in HSV, which maps closely to how colour pickers behave.

No. Colour conversion is pure math done in your browser — nothing is sent anywhere.

Use HEX or RGB for CSS. HSV is great while you're choosing and adjusting a colour. Save CMYK and Pantone for print and brand specifications.
