Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. 1. RGB ÷ 255

   R = 0.0000
   G = 0.4118
   B = 0.6588

2. 2. max, min, Δ

   max = 0.6588
   min = 0.0000
   Δ = max − min = 0.6588

3. 3. L

   L = (max + min) / 2 = 0.3294 = 32.94%

4. 4. S

   S = Δ / (1 − |2L − 1|) = 1.0000 = 100.00%

5. 5. H

   max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.0000 − 0.4118) / 0.6588 + 4) = 202.50°

6. 6. HSL

   hsl(202.50 100.00% 32.94%)
