How HEX to RGB conversion works
A HEX color like #2D5BE3 is three two-digit base-16 numbers: red 2D, green 5B, blue E3. Convert each pair to decimal (first digit × 16 + second digit): 2D = 2×16 + 13 = 45, 5B = 5×16 + 11 = 91, E3 = 14×16 + 3 = 227. So #2D5BE3 = rgb(45, 91, 227).
Short 3-digit HEX doubles each digit: #ABC is #AABBCC = rgb(170, 187, 204). An 8-digit HEX such as #2D5BE380 adds an alpha pair (80 = 128 ≈ 50% opacity).
