Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0078
G = 0.0235
B = 0.0941
```

2. max, min, Δ

max = 0.0941
min = 0.0078
Δ = max − min = 0.0863

3. L
```
L = (max + min) / 2 = 0.0510 = 5.10%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8462 = 84.62%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.0078 − 0.0235) / 0.0863 + 4) = 229.09°

6. HSL
```
hsl(229.09 84.62% 5.10%)
```
