Convert colors between HEX, RGB and HSL
Paste a color in HEX, RGB, or HSL and get every equivalent format back instantly.
For the best results: Paste any format (#hex, rgb() or hsl()) and every equivalent comes back, plus a hint on whether dark or light text reads better on that color.
Runs entirely in your browser, what you paste is never uploaded, logged, or stored.
What is Color Converter?

See it in action
A brand gold defined as hex needs its RGB and HSL forms for a stylesheet.
What you type
#CBAA4E
What you get
rgb(203, 170, 78) and hsl(44, 55%, 55%), each self-consistent when converted back, plus a relative-luminance readout advising which text color reads best on it.
Tip: Shorthand hex like #abc expands automatically to #aabbcc. Round trips through HSL can shift a channel by one point, that is integer rounding in the color math, not an error.
Use cases
What people use it for
Translate a brand HEX code into RGB values for a design tool that expects them.
Convert CSS colors into HSL so you can lighten or darken them predictably in code.
Check a color's contrast hint before putting text over it on a slide or webpage.
Who uses Color Converter?
Front-end developers
juggle HEX in stylesheets, RGB in scripts, and HSL for hover states, themes, and design tokens.
Graphic designers
match brand colors across tools where each application insists on a different color format from the last.
Content creators
pick readable text and background combinations for presentations, social tiles, marketing graphics, and internal documents.
How it works
- 1Vary step 1 by tool shape using the existing FORM_TOOL_IDS set in app/(public)/[category]/[tool]/page.tsx. Form tools get "Set the options for what you need." and text tools get "Paste your text into the box." Where a tool's config makes it easy, name its own inputs instead. Steps 2 and 3 stay shared as they are.
- 2Your browser computes the result instantly. Nothing is uploaded anywhere.
- 3Copy the output; the tool keeps working even offline.
Tips for the best results
- Store brand colors in one canonical format and convert as needed, not from memory.
- Reach for HSL when creating tints and shades: adjust lightness, keep hue fixed.
- Heed the contrast hint before layering text on a background color.
- Remember shorthand three-digit HEX doubles each digit, so F80 means FF8800.
- Check colors on more than one screen before signing off brand work.
FAQ
Frequently asked questions
What is a HEX color code, really?
It is RGB wearing hexadecimal clothing. The six characters split into three pairs for red, green, and blue, each running from 00 to FF, which is 0 to 255 in decimal. So converting HEX to RGB does not change the color model at all, only the number base. HSL, by contrast, is a genuinely different way of describing the same color.
When should I use HSL instead of RGB?
Whenever you want to adjust a color rather than merely specify it. HSL separates hue, expressed as an angle, from saturation and lightness, so making a button darker on hover means nudging one number. In RGB you would need to shift all three channels in careful proportion to achieve the same visual effect.
What does the contrast hint tell me?
It indicates whether text would stay readable against the color, essentially whether light or dark lettering suits it. Contrast is the ratio of relative luminance between foreground and background, and accessibility guidelines such as WCAG set minimum ratios for body text. A quick hint at conversion time catches unreadable pairings before they ship anywhere.
Why do the same RGB numbers look different on another screen?
Because RGB values are instructions to a display, and displays differ in calibration, gamut, and brightness. Most of the web assumes the sRGB color space, but wide-gamut monitors stretch those same numbers further. For critical brand work, view colors on the sort of devices your audience actually uses rather than trusting a single screen.
Do my color values get sent to a server for conversion?
The math, a few lines of arithmetic per conversion, runs directly inside the page, so nothing you enter goes anywhere at all. That is partly why results update the moment you type. An unreleased brand palette stays confidential, and the converter keeps functioning with the network switched off entirely, since it has no server to miss.
How do I convert HEX to RGB manually?
Split the six characters into pairs, then convert each pair from base sixteen: multiply the first digit by sixteen and add the second, where A through F stand for ten through fifteen. FF becomes 255 and 80 becomes 128. Entirely doable by hand, and precisely the tedium this converter removes.
What is the difference between HSL and HSV?
Both models treat hue as an angle, but they handle brightness differently. HSL runs lightness from black through the pure color up to white, so full lightness is always white. HSV's value axis peaks at the vivid color instead. CSS supports HSL natively, which is why web tooling standardized on it.
What HEX color is pure white?
FFFFFF, all three channels at maximum, usually written with a leading hash. Black is the opposite at 000000, and any code with three equal pairs, such as 808080, lands on a neutral gray. Pure white converts to RGB 255, 255, 255 and to an HSL lightness of one hundred per cent.
Are there any usage limits?
None. Everything is generated locally in your browser, so there is no server cost, no metering, and no daily cap, use it as many times as you like, completely free.
