How do I convert colors between HEX, RGB, and HSL?

Enter a color in any format — HEX (#ff6600), RGB (rgb(255, 102, 0)), or HSL (hsl(24, 100%, 50%)) — and instantly see it converted to all other formats. The tool includes a live color preview and lets you copy any value with one click.

Color Converter

Convert colors between HEX, RGB, and HSL formats.

Tips & Best Practices

Pro Tip

HSL is the most intuitive model for UI design

HSL separates hue (the color), saturation (intensity), and lightness (brightness). To create a darker button hover state, reduce lightness by 10%. To create a muted variant, reduce saturation. In HEX/RGB you'd need to adjust all three channels — HSL makes systematic color palettes trivial.

Common Pitfall

HEX shorthand can cause subtle color differences

#333 expands to #333333, but #123 expands to #112233 — not #010203. Each digit is doubled, not treated as the first digit of a two-digit pair. This catches designers who assume #1A2 means a color close to #1A2000 when it actually becomes #11AA22.

Real-World Example

CSS oklch() is the future of web color

The oklch() color function (supported in all modern browsers since 2023) provides perceptually uniform colors. Unlike HSL where lightness: 50% produces visually different brightness for different hues, oklch guarantees consistent perceived brightness. This is why a yellow and blue at the same HSL lightness look completely different.

Pro Tip

Use 8-digit HEX for alpha transparency

Instead of rgba(255, 0, 0, 0.5), use #FF000080. The last two hex digits represent alpha (00 = transparent, FF = opaque). 80 in hex is 128 in decimal, or 50% opacity. This is supported in all modern browsers and keeps your CSS consistent with the HEX format.

Frequently Asked Questions

How do I convert a HEX color to RGB?
Enter your HEX color code (e.g., #3B82F6) into the input field and the tool instantly displays the equivalent RGB, HSL, and other color format values. HEX codes represent colors using hexadecimal values for red, green, and blue channels. Each pair of hex digits maps to a 0-255 RGB value. For example, #FF0000 converts to RGB(255, 0, 0) because FF in hexadecimal equals 255 in decimal. DevBolt's Color Converter handles shorthand HEX codes like #F00, 8-digit HEX with alpha (#FF000080), and validates input in real time. The conversion runs entirely in your browser.
What is the difference between HEX, RGB, and HSL color formats?
HEX, RGB, and HSL represent the same colors using different notation systems. HEX uses a six-character hexadecimal string prefixed with # and is the most common format in CSS. RGB specifies red, green, and blue channel values from 0 to 255, making it intuitive for programmatic color manipulation. HSL defines colors by hue (0-360 degrees on the color wheel), saturation (0-100%), and lightness (0-100%), making it easiest for adjusting brightness or vibrancy. All three formats represent 16.7 million colors. Choose HEX for compact CSS declarations, RGB for channel-level manipulation in code, and HSL when you need to create lighter or darker variants of a color.
Can I convert colors with transparency (alpha channel)?
Yes, DevBolt's Color Converter supports alpha channel conversions across all formats. You can input 8-digit HEX codes (e.g., #3B82F680 where the last two digits represent opacity), RGBA values (e.g., rgba(59, 130, 246, 0.5)), or HSLA values (e.g., hsla(217, 91%, 60%, 0.5)). The alpha channel represents opacity on a scale from 0 (fully transparent) to 1 (fully opaque). In 8-digit HEX, the last two characters encode the alpha as a hexadecimal value from 00 (transparent) to FF (opaque). The tool converts the alpha value accurately between all supported formats.
