Step-by-step math

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

1. RGB ÷ 255
```
R = 0.8039
G = 0.3608
B = 0.3608
```

2. max, min, Δ

max = 0.8039
min = 0.3608
Δ = max − min = 0.4431

3. L
```
L = (max + min) / 2 = 0.5824 = 58.24%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.5305 = 53.05%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.3608 − 0.3608) / 0.4431) mod 6) = 0.00°

6. HSL
```
hsl(0.00 53.05% 58.24%)
```
