Color Converters
Convert between every colour model designers and developers use — HEX, RGB, HSV, CMYK and Pantone — with live previews and exact values.
RGB to HEX
Web's most common conversion — RGB triplets to a #hex code.
RGB to HSV
Move from RGB to hue/saturation/value for intuitive editing.
RGB to CMYK
Approximate print-ready CMYK ink values from screen RGB.
RGB to Pantone
Find the closest Pantone PMS match for an RGB colour.
HEX to RGB
Expand a #hex code into red, green and blue channels.
HEX to HSV
Read a hex colour as hue, saturation and value.
HEX to CMYK
Translate a web hex colour toward print CMYK.
HEX to Pantone
Match a hex colour to the nearest Pantone swatch.
CMYK to RGB
Bring print CMYK values back to screen RGB.
CMYK to HEX
Get a web hex code from CMYK ink percentages.
CMYK to HSV
Convert CMYK into the HSV model.
CMYK to Pantone
Find the closest Pantone match for a CMYK mix.
Pantone to RGB
Turn a Pantone code into usable RGB values.
Pantone to HEX
Get the web hex equivalent of a Pantone colour.
Pantone to HSV
Read a Pantone colour as hue, saturation and value.
Pantone to CMYK
Approximate the CMYK build of a Pantone colour.
HSV to RGB
Convert hue/saturation/value back to RGB.
HSV to HEX
Get a hex code from HSV values.
HSV to CMYK
Move from HSV toward print-oriented CMYK.
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.
