One color, every format
Pick an input model, then read the same color as hex, RGB, HSL, HSV and CMYK. HueKit also builds shades, tints and classic harmonies so you can grow a palette from a single starting color.
Choosing the right color model
Every color model describes the same visible colors, but each one makes a different task easy. Knowing which to reach for saves a lot of guesswork.
RGB and hex, for screens
RGB mixes red, green and blue light. It is how displays actually work, and hex is simply a shorter way to write the same three channels. Use them for anything that ends up on a screen. If you only need this one jump, the focused hex to RGB converter is the quickest route.
HSL and HSV, for adjusting
HSL and HSV both separate hue from saturation and lightness. That makes them the friendly models when you want to nudge a color: keep the hue, drop the lightness, and you get a clean shade. Designers reach for HSL constantly when building consistent scales.
CMYK, for print
CMYK describes ink on paper: cyan, magenta, yellow and a key black. If your work is heading to a printer, CMYK is the model that matters, but always confirm against your print provider's profile before a big run.
Building a palette from one color
The harmonies under the readout are a practical shortcut. Start with a brand color, take its complementary for accents, and pull an analogous pair for softer supporting tones. The shade and tint strip gives you a ready made light to dark scale for backgrounds and borders.
Frequently asked questions
Which color models does this converter support?
HueKit converts between five models: hex, RGB, HSL, HSV and CMYK. Change any one of them and the other four update instantly, so you always see the full picture of a single color.
Why do CMYK values look approximate?
CMYK is a print model and screens are RGB, so there is no single exact mapping. HueKit uses the standard naive conversion, which is fine for previewing. For production print, trust your printer's ICC profile.
What are complementary, analogous and triadic colors?
They are harmonies built by rotating the hue. Complementary sits opposite on the wheel, analogous sits just beside your color, and triadic spaces three colors evenly. They are a fast starting point for a palette.
Does the converter work offline?
Yes. All the math runs in your browser, so once the page has loaded you can keep converting with no network connection.
