How to Use the Color Converter:
Enter your color in any supported format (RGB, CMYK, HSL, HEX, or color name). The tool automatically converts it to all other formats in real-time. Use the color picker for visual selection, or paste values directly. Perfect for converting web colors (RGB/HEX) to print colors (CMYK) or adjusting colors in CSS.
- Web to Print Conversion
Convert RGB colors from web designs to CMYK for print production, ensuring accurate color reproduction.
- CSS Development
Convert between HEX, RGB, and HSL formats when writing CSS for WordPress themes and custom styles.
- Design Consistency
Maintain consistent colors across digital and print media by converting between color spaces accurately.
- Accessibility Testing
Convert colors to different formats to test contrast ratios and ensure WCAG compliance for web accessibility.
How Do Color Spaces Work?
Different color spaces represent colors using different methods. RGB uses additive color mixing for screens, CMYK uses subtractive mixing for print, HSL represents colors by hue, saturation, and lightness, while HEX is a hexadecimal representation of RGB values. Understanding these differences is crucial for accurate color conversion.
- RGB (Red, Green, Blue)Additive color model used for screens and digital displays. Colors are created by adding light—combining red, green, and blue light at different intensities (0-255 each). RGB has a wider color gamut than CMYK, making it ideal for web and digital media.
- CMYK (Cyan, Magenta, Yellow, Key/Black)Subtractive color model used for print production. Colors are created by subtracting light—mixing cyan, magenta, yellow, and black inks (0-100% each). CMYK has a narrower gamut than RGB, so some bright RGB colors cannot be accurately reproduced in print.
- HSL (Hue, Saturation, Lightness)Intuitive color model that represents colors by their hue (0-360°), saturation (0-100%), and lightness (0-100%). HSL makes it easier to adjust color properties—you can change brightness without affecting hue, or adjust saturation independently.
- HEX (Hexadecimal)Six-digit hexadecimal code representing RGB values (e.g., #FF5733). Each pair of characters represents red, green, and blue values from 00 to FF (0-255 in decimal). HEX is compact and widely used in web development and CSS.
- Color Gamut DifferencesRGB can display more vibrant colors than CMYK. When converting RGB to CMYK, some colors may appear duller or shift because CMYK cannot reproduce all RGB colors. This is why web colors often need adjustment for print.
Using Color Conversion in JavaScript:
function rgbToHex(r, g, b) {
return "#" + [r, g, b]
.map(x => x.toString(16).padStart(2, "0"))
.join("");
}
const hex = rgbToHex(255, 87, 51);
console.log(hex);#FF5733function hexToRgb(hex) {
const result = /^#?([a-fd]{2})([a-fd]{2})([a-fd]{2})$/i.exec(hex);
return result ? {
r: parseInt(result[1], 16),
g: parseInt(result[2], 16),
b: parseInt(result[3], 16)
} : null;
}
const rgb = hexToRgb("#FF5733");
console.log(rgb);{r: 255, g: 87, b: 51}function rgbToHsl(r, g, b) {

const max = Math.max(r, g, b);

Frequently Asked Questions
What is the difference between RGB and CMYK?
RGB is an additive color model used for screens (adding light creates colors), while CMYK is subtractive used for print (subtracting light with ink). RGB has a wider color gamut, so some RGB colors cannot be accurately reproduced in CMYK print.
Why do colors look different in print vs screen?
Screens emit light (RGB), while print reflects light (CMYK). CMYK has a narrower color gamut, so bright RGB colors often appear duller when printed. Always convert RGB to CMYK before printing for accurate results.
What is HSL and when should I use it?
HSL (Hue, Saturation, Lightness) is intuitive for color manipulation. Use HSL when you need to adjust brightness without changing hue, or when creating color variations programmatically in CSS or JavaScript.
How do I convert HEX to RGB?
Each pair of HEX characters represents RGB values. For example, #FF5733 means FF (255) red, 57 (87) green, 33 (51) blue. Use our converter or parse the hex string into decimal values.
Can all RGB colors be printed in CMYK?
No. CMYK has a narrower color gamut than RGB. Bright, saturated colors (especially neon greens, cyans, and magentas) often cannot be accurately reproduced in CMYK and will appear duller when printed.
What does the "K" in CMYK stand for?
K stands for “Key” (black). It’s called “key” because black is the key color used for text and detail in printing. The K avoids confusion with Blue (B) in RGB.
