What color formats does ColorSwitch support?

ColorSwitch converts between four color formats: HEX (#ec4899), RGB (rgb(236, 72, 153)), HSL (hsl(330, 81%, 60%)), and OKLCH (oklch(0.656 0.199 349.8)). All conversions happen instantly as you type.

What is OKLCH and why should I use it?

OKLCH is a modern CSS color format based on the OKLab perceptual color space. Unlike HSL, OKLCH provides perceptually uniform lightness and chroma, meaning colors with the same L value actually look equally bright. It's supported in all modern browsers (Chrome 111+, Safari 15.4+, Firefox 113+) and is the recommended format for CSS color manipulation in 2026.

Is my color data private?

Yes, 100%. ColorSwitch runs entirely in your browser using JavaScript. No color data is sent to any server. Everything is processed locally on your device.

How do I convert HEX to RGB?

Simply paste or type your HEX color code (e.g., #ec4899) into the HEX input field. The RGB values will update automatically. You can also use the color picker to visually select a color and see all format conversions instantly.

What's the difference between HEX and RGB?

HEX and RGB represent the same information differently. HEX uses hexadecimal notation (#RRGGBB), while RGB uses decimal values (rgb(R, G, B)). Both specify red, green, and blue channel values from 0-255. HEX is more compact, RGB is more human-readable.

Why do some colors look different in OKLCH?

When converting to OKLCH and back, very slight rounding differences may occur because OKLCH uses a perceptual color model that doesn't map 1:1 to sRGB. These differences are typically imperceptible (less than 1 unit in RGB values).

Can I use the color picker on mobile?

Yes! The color preview box acts as a color picker. Tap it on mobile to open your device's native color picker. All formats update in real time as you select colors.

Do I need to include the # symbol for HEX colors?

It's optional. ColorSwitch accepts HEX values with or without the # prefix, and supports both 3-digit (#f0f) and 6-digit (#ff00ff) shorthand. The output always includes the # prefix.

Frequently Asked Questions

About ColorSwitch

ColorSwitch is a free color format converter built for designers, front-end developers, and anyone who works with CSS colors. Whether you need to convert a hex code from a design file to RGB for JavaScript, or try the new oklch() function for CSS Color Level 4, ColorSwitch handles all four major formats instantly.

What makes ColorSwitch unique is OKLCH support. While most color converters only handle HEX, RGB, and HSL, ColorSwitch includes the OKLCH color space — the perceptually uniform format recommended by the CSS Color Level 4 specification. OKLCH produces more predictable results when adjusting lightness and saturation, making it ideal for design systems and accessible color palettes.

All conversions run entirely in your browser — no data is sent to any server. ColorSwitch features a visual color picker, real-time format updates, one-click CSS copy, and supports both light and dark themes. It's the color tool you'll keep open all day.
