Step-by-step math

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

1. RGB ÷ 255
```
R = 0.8627
G = 0.1490
B = 0.1490
```

2. max, min, Δ

max = 0.8627
min = 0.1490
Δ = max − min = 0.7137

3. L
```
L = (max + min) / 2 = 0.5059 = 50.59%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.7222 = 72.22%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.1490 − 0.1490) / 0.7137) mod 6) = 0.00°

6. HSL
```
hsl(0.00 72.22% 50.59%)
```
