Step-by-step math

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

1. RGB ÷ 255
```
R = 0.1137
G = 0.0863
B = 0.1176
```

2. max, min, Δ

max = 0.1176
min = 0.0863
Δ = max − min = 0.0314

3. L
```
L = (max + min) / 2 = 0.1020 = 10.20%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.1538 = 15.38%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.1137 − 0.0863) / 0.0314 + 4) = 292.50°

6. HSL
```
hsl(292.50 15.38% 10.20%)
```
