How colour formats relate
HEX is the red, green and blue channels written as three base-16 pairs: #3B82F6 means R = 0x3B = 59, G = 0x82 = 130, B = 0xF6 = 246. HSL describes the same colour as hue (0 to 360 degrees on the colour wheel), saturation and lightness in percent. HSV is similar with value instead of lightness. CMYK is the subtractive print model: cyan, magenta, yellow and black. CMYK values from screen RGB are approximations because printers have a different gamut.
Worked example
#3B82F6 in every format
| HEX | #3B82F6 |
| RGB | rgb(59, 130, 246) |
| HSL | hsl(217, 91%, 60%) |
| Common colours | #FF0000 = rgb(255,0,0); #FFFFFF = rgb(255,255,255); #000000 = rgb(0,0,0) |

Tips and common mistakes
- Use HSL when you need lighter or darker versions of a colour: change only L.
- 3-digit hex like #f60 expands to #ff6600.
- 8-digit hex adds alpha: #3B82F680 is 50% transparent.
- Printed colours rarely match the screen exactly; request a proof.
- Name your colours as CSS variables.
