Step-by-step math

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

1. 1. RGB ÷ 255

   R = 0.9529
   G = 0.9451
   B = 0.9451

2. 2. max, min, Δ

   max = 0.9529
   min = 0.9451
   Δ = max − min = 0.0078

3. 3. L

   L = (max + min) / 2 = 0.9490 = 94.90%

4. 4. S

   S = Δ / (1 − |2L − 1|) = 0.0769 = 7.69%

5. 5. H

   max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.9451 − 0.9451) / 0.0078) mod 6) = 0.00°

6. 6. HSL

   hsl(0.00 7.69% 94.90%)
