Step-by-step math

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

1. RGB ÷ 255
```
R = 0.2118
G = 0.2549
B = 0.3255
```

2. max, min, Δ

max = 0.3255
min = 0.2118
Δ = max − min = 0.1137

3. L
```
L = (max + min) / 2 = 0.2686 = 26.86%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.2117 = 21.17%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.2118 − 0.2549) / 0.1137 + 4) = 217.24°

6. HSL
```
hsl(217.24 21.17% 26.86%)
```
