Step-by-step math

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

1. 1. RGB ÷ 255

   R = 0.0000
   G = 0.3922
   B = 0.0000

2. 2. max, min, Δ

   max = 0.3922
   min = 0.0000
   Δ = max − min = 0.3922

3. 3. L

   L = (max + min) / 2 = 0.1961 = 19.61%

4. 4. S

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

5. 5. H

   max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.0000 − 0.0000) / 0.3922 + 2) = 120.00°

6. 6. HSL

   hsl(120.00 100.00% 19.61%)
