Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0078
G = 0.1725
B = 0.1333
```

2. max, min, Δ

max = 0.1725
min = 0.0078
Δ = max − min = 0.1647

3. L
```
L = (max + min) / 2 = 0.0902 = 9.02%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9130 = 91.30%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.1333 − 0.0078) / 0.1647 + 2) = 165.71°

6. HSL
```
hsl(165.71 91.30% 9.02%)
```
