Step-by-step math

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

1. RGB ÷ 255
```
R = 0.7216
G = 0.5255
B = 0.0431
```

2. max, min, Δ

max = 0.7216
min = 0.0431
Δ = max − min = 0.6784

3. L
```
L = (max + min) / 2 = 0.3824 = 38.24%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8872 = 88.72%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.5255 − 0.0431) / 0.6784) mod 6) = 42.66°

6. HSL
```
hsl(42.66 88.72% 38.24%)
```
