Color Converter
Convert colors between HEX RGB and HSL.

What Is the Color Converter?
A color converter translates between HEX, RGB, and HSL color formats so the same hue moves cleanly between design tools, code, and print workflows. Web CSS favors hex triplets like #1E3A8A, programming APIs often want RGB channel numbers, and designers adjust colors more intuitively in HSL's hue, saturation, and lightness model. All three describe identical colors differently: hex packs channels into two digit base sixteen pairs, RGB states each channel from 0 to 255, and HSL describes position on a color wheel instead. This tool converts instantly in every direction and shows the underlying channel values so you can tweak colors deliberately.
Key Statistics

16.7 million
Distinct colors expressible in standard six digit hex notation

-
255
Maximum value of any single RGB channel

The Formula
HEX: #RRGGBB. RGB: values 0-255. HSL: Hue Saturation Lightness.
Worked Examples
The color deep sky blue has HEX code #00BFFF which converts to RGB values of 0 red, 191 green, and 255 blue. In HSL this translates to 195 degrees hue, 100% saturation, and 50% lightness. Midnight blue #191970 becomes RGB 25, 25, 112 and HSL 240 degrees, 64% saturation, 27% lightness, making these conversions essential for consistent web and print design work.
Hex to RGB decoding
- Take the navy shade #1E3A8A
- Split into byte pairs: 1E, 3A, 8A
- Convert each pair from hexadecimal
The RGB channels are 30, 58, and 138.
Real World Use Cases
Frontend development
Move brand colors between CSS hex values and RGB functions in code.
Design system work
Generate HSL variations for hover states and dark mode palettes from base colors.
Digital art workflows
Match colors across applications that prefer different notations.
Expert Tips
- ✓ Shorthand hex like #F00 expands to #FF0000 when each digit doubles.
- ✓ HSL makes tints and shades trivial: hold hue and saturation, then slide lightness.
- ✓ Complementary colors sit 180 degrees apart in hue, useful for accessible contrast pairings.
- ✓ Screen RGB and print CMYK describe different gamuts; expect shifts when printing saturated screen colors.
Frequently Asked Questions
What is the difference between HEX and RGB color codes? ▼
Both describe the same red, green, and blue channels. HEX writes each channel as a two digit base 16 value, like FF, while RGB writes them as decimal numbers from 0 to 255.
How do I convert HEX to RGB? ▼
Split the hex code into three pairs, then convert each pair from base 16 to decimal. The hex code 3366FF becomes RGB with red 51, green 102, and blue 255.
What is HSL? ▼
HSL describes color by hue, saturation, and lightness. Hue is the color angle from 0 to 360, and saturation and lightness are percentages. It is often easier than RGB for choosing pleasing colors.
How do I convert RGB to HEX? ▼
Convert each RGB channel from decimal to a two digit hex value, then join them. RGB with red 255, green 0, and blue 0 becomes the hex code FF0000, which is pure red.
What do color codes mean? ▼
Each code is a recipe for a color on a screen. RGB and HEX mix red, green, and blue light, while CMYK mixes ink colors for print. Changing any channel value changes the resulting color.
What is the difference between RGB and CMYK? ▼
RGB uses additive light mixing for screens, where combining all channels gives white. CMYK uses subtractive ink mixing for print, where combining all colors gives black. Convert between them when moving designs from screen to paper.
How do I convert HEX to RGB? ▼
Split the six digit code into three pairs, convert each two digit hexadecimal value to decimal, and read them as red, green, and blue channels.
What does HSL mean? ▼
Hue sets the color's position on the wheel in degrees, saturation controls intensity, and lightness ranges from black through the pure color to white.
Common Mistakes to Avoid
- ⚠ Omitting the hash symbol when entering a HEX color code. The converter expects the hash prefix to identify the input as hex. Entering FF5733 without the hash may be interpreted as something other than a hex color, producing an incorrect or empty conversion.
- ⚠ Typing a three-digit hex shorthand like #F30 instead of the full six-digit equivalent #FF3300. Both represent valid CSS colors but expand differently. The converter may treat a three-digit code as invalid if it expects the six-digit standard format.
- ⚠ Assuming the RGB values from the converter match print output exactly. The converter works in the RGB color space designed for screens. CMYK print colors have a different gamut, so a vibrant screen blue may print as a dull purple without additional print color management.
- ⚠ Editing hex digits blindly. Changing a single character shifts one channel unpredictably, so convert to RGB or HSL first for controlled adjustments.
