Does the tool support colors with transparency?

Yes, the tool fully handles alpha channels. You can convert between RGBA and HSLA and see the transparency visually in the preview. The alpha value is preserved correctly in all formats that support it.

Can I use CSS color names as input?

Yes, the tool recognizes all 147 CSS color names — from "aliceblue" to "yellowgreen". Enter the color name and get it converted to HEX, RGB, HSL and all other formats.

What is the difference between RGB and HSL?

RGB (Red, Green, Blue) defines colors based on the amount of red, green and blue light. HSL (Hue, Saturation, Lightness) defines colors based on hue, saturation and lightness — which is more intuitive for adjusting colors visually.

Can I generate color palettes?

Yes, the tool can generate complementary colors, analogous colors, triadic colors and monochromatic variants based on your input color — useful for building harmonious color palettes for websites and brands.

Color Converter

What it does

Converts color values between HEX, RGB, HSL and other formats. Shows color preview.

Color values exist in many formats — and manual conversion is error-prone and time-consuming

Designers work in HEX, CSS uses RGB or HSL, Figma exports in one format and code requires another. Every time you move a color between tools or contexts you need to convert it. Manual conversion with formulas or Google searches is slow and error-prone — an error in a single value gives the wrong color, and you might not notice until it is too late.

Design tools export in HEX while CSS code needs RGB with alpha channel — and you need to convert manually for every single color in the design system
HSL values are intuitive for color manipulation but hard to convert mentally — adjusting brightness or saturation requires understanding the relationship between components
Errors in color conversion are hard to detect visually — a small rounding error gives a color that looks almost right but does not match the design system exactly
Team members use different formats — the designer sends HEX, the developer needs RGB, and the marketer wants the color name for brand guidelines

Instant color conversion between all common formats — with visual preview

Color Converter lets you paste a color value in any format and get it instantly converted to all other formats. Enter #FF5733 and get RGB(255, 87, 51), HSL(11, 100%, 60%), and more — all with a visual preview so you can confirm the color is correct before using it.

All formats supported: HEX, RGB, RGBA, HSL, HSLA, HSV, CMYK and CSS color names — convert between all with one click
Visual preview: see the color visually while converting so you can immediately confirm the result is correct
Copy-ready output: click on a format to copy the finished formatted color value directly to your clipboard — ready to paste into CSS, Figma or design documents
Alpha channel support: convert colors with transparency between RGBA and HSLA formats without losing alpha information

Features

Universal input: enter the color in any format — HEX with or without #, RGB with or without parentheses, HSL, color names like "coral" or "steelblue" — the tool recognizes the format automatically
All formats simultaneously: see the color converted to HEX, RGB, RGBA, HSL, HSLA, HSV and CMYK simultaneously so you can copy the format you need without doing multiple conversions
Color palette generator: generate complementary colors, analogous colors and triadic colors based on the input color — useful for building harmonious color palettes
Contrast check: see the contrast ratio between the color and white/black background to ensure text is readable according to WCAG guidelines

How it works

Enter or paste a color value in any format — HEX (#FF5733), RGB (255, 87, 51), HSL (11, 100%, 60%) or a CSS color name like "tomato"
See the color visually and get it automatically converted to all available formats — HEX, RGB, RGBA, HSL, HSLA, HSV and CMYK
Click on the format you need to copy it to your clipboard — paste directly into your CSS file, design tool or brand guidelines

Use cases

Frontend developers who need to convert designer HEX colors to RGB or HSL for CSS variables, animations or dynamic color manipulation in JavaScript
Designers building design systems who need consistent color values across Figma (HEX), CSS (RGB/HSL) and print files (CMYK)
Marketers updating brand guidelines who need all color formats documented — HEX for web, RGB for presentations and CMYK for print

Why use Color Converter?

Color conversion is one of those tasks that seems trivial but takes surprisingly much time when done manually. Every time you copy a color from Figma to CSS, from brand guidelines to a presentation, or from web to print, you need to convert the format. Color Converter does this instantly.

For developers the tool is especially useful when working with CSS variables and needing to manipulate colors dynamically. HSL format makes it easy to adjust brightness and saturation, but you need HEX for design tokens and RGB for canvas operations. With Color Converter you have all formats available instantly.

The contrast check is a bonus that helps you ensure your color combinations meet WCAG requirements for accessibility — which is both legally required and good practice for user experience.
