How this calculation works
The Color Code Converter translates web and print color specifications between HEX hexadecimal, RGB decimal, HSL cylindrical, and CMYK print ink standards.
Mathematical formula and logic
R = hex[1..2], G = hex[3..4], B = hex[5..6]. HSL is computed via trigonometric rgb-max-min chromatic transformation.
Worked example
The emerald color #08A878 converts to: RGB(8, 168, 120), HSL(162°, 91%, 35%), and CMYK(95%, 0%, 29%, 34%).
Calculation assumptions
- sRGB standard color space used in modern web browsers (CSS Color Level 4).
- Standard 8-bit color channels (0 to 255 range).
Frequently asked questions
Why do web designers prefer HSL over RGB or HEX?
HSL (Hue, Saturation, Lightness) aligns with human visual perception. It makes adjusting color brightness or creating harmonious palette tints/shades intuitive by simply tweaking the lightness percentage.
What is the difference between RGB and CMYK?
RGB is an additive color model used for digital screens (light emitted). CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive model used for physical ink printing.
What does an 8-digit HEX code represent?
An 8-digit HEX code includes a 2-digit alpha transparency channel at the end (e.g. #08A87880 represents 50% opacity).
What is WCAG color contrast ratio?
The Web Content Accessibility Guidelines (WCAG 2.1) require a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text against background colors to ensure readable accessibility.
Can RGB values exceed 255?
In standard 8-bit sRGB color spaces, values are strictly constrained between 0 and 255. Wide-gamut color spaces (like Display P3 or Rec.2020) allow extended color gamuts.
