Step-by-step math

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

1. 1. RGB ÷ 255

   R = 0.2627
   G = 0.1765
   B = 0.8431

2. 2. max, min, Δ

   max = 0.8431
   min = 0.1765
   Δ = max − min = 0.6667

3. 3. L

   L = (max + min) / 2 = 0.5098 = 50.98%

4. 4. S

   S = Δ / (1 − |2L − 1|) = 0.6800 = 68.00%

5. 5. H

   max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.2627 − 0.1765) / 0.6667 + 4) = 247.76°

6. 6. HSL

   hsl(247.76 68.00% 50.98%)
