What Is HEX Color?

HEX color notation uses hexadecimal (base-16) numbers to express RGB values. Each pair of characters represents one channel (R, G, B) from 00 (0) to FF (255). Example: #FF5733 = R:255, G:87, B:51.

How to Convert HEX to RGB

1. Split the HEX code into three pairs: FF, 57, 33
2. Convert each pair from base-16 to base-10:
   • FF = 15×16 + 15 = 255
   • 57 = 5×16 + 7 = 87
   • 33 = 3×16 + 3 = 51
3. Result: rgb(255, 87, 51)

How to Convert RGB to HEX

1. Convert each channel value from decimal to hex:
   • 255 → FF
   • 87 → 57
   • 51 → 33
2. Concatenate with # prefix: #FF5733

Shorthand HEX

When each pair is the same digit (e.g., #FFAABB), you can write a 3-digit shorthand: #FAB. Browsers expand this to #FFAABB. Only works when each channel pair is a doubled digit.
