HEX, RGB and HSL Color Converter
Convert colors between HEX codes, RGB values and HSL. For programming LED strips, WLED configurations, web design, or any RGB lighting project.
Last updated: May 2026
HEX: #FF5733 | RGB: 255, 87, 51 | HSL: 11°, 100%, 60%
How to use this color converter
Enter a color in any format and see it converted to all others instantly. The color preview updates live. Copy the HEX code for web design, RGB values for LED controllers, or HSL for color manipulation. Common use: a designer sends you #FF5733 but your WLED setup needs three separate 0-255 values.
Common color formats explained
| Format | Example | Range | Common use |
|---|---|---|---|
| HEX | #FF5733 | 00-FF per channel | Web design, CSS |
| RGB | 255, 87, 51 | 0-255 per channel | LED strips, microcontrollers |
| HSL | 11°, 100%, 60% | H: 0-360°, S/L: 0-100% | Color adjustments, UI sliders |
When you need this tool
Your WLED controller needs RGB values but the color palette is in HEX. Or you're programming an ESP32 NeoPixel strip where the code expects three bytes (0-255) but your reference is #3498DB. Or you're matching a brand color across web and physical LED installations. Convert between formats here.
Frequently Asked Questions
Why are there three different color formats?
Each format serves different purposes: HEX is readable and compact for web design and CSS. RGB is what electronic displays use internally, each value (0-255) controls one color channel. HSL is intuitive for humans, hue is the color, saturation is intensity, and lightness is brightness. Different tools expect different formats.
Can I input HEX colors without the # symbol?
Yes. The converter accepts HEX codes with or without the leading # symbol. Both FF5733 and #FF5733 will work. The format is flexible to match how colors appear in different contexts.
How do I use RGB values in LED strip code?
Most LED libraries (NeoPixel, WLED, Addressable RGB) accept RGB as three separate decimal values from 0-255. For example, RGB(255, 87, 51) sets the LED to orange. Copy the individual R, G, B values from this converter into your code.
What is the relationship between HEX and RGB?
HEX is just hexadecimal notation for RGB. HEX uses two hex digits per channel (00-FF), while RGB uses decimal (0-255). FF in hex equals 255 in decimal. They represent the exact same color, just in different number systems.
