Step-by-step math

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

1. RGB ÷ 255
```
R = 0.5451
G = 0.0314
B = 0.2118
```

2. max, min, Δ

max = 0.5451
min = 0.0314
Δ = max − min = 0.5137

3. L
```
L = (max + min) / 2 = 0.2882 = 28.82%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8912 = 89.12%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.0314 − 0.2118) / 0.5137) mod 6) = 338.93°

6. HSL
```
hsl(338.93 89.12% 28.82%)
```
