Step-by-step math

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

1. RGB ÷ 255
```
R = 0.1137
G = 0.0941
B = 0.0863
```

2. max, min, Δ

max = 0.1137
min = 0.0863
Δ = max − min = 0.0275

3. L
```
L = (max + min) / 2 = 0.1000 = 10.00%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.1373 = 13.73%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.0941 − 0.0863) / 0.0275) mod 6) = 17.14°

6. HSL
```
hsl(17.14 13.73% 10.00%)
```
