Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6235
G = 0.0275
B = 0.0706
```

2. max, min, Δ

max = 0.6235
min = 0.0275
Δ = max − min = 0.5961

3. L
```
L = (max + min) / 2 = 0.3255 = 32.55%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9157 = 91.57%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.0275 − 0.0706) / 0.5961) mod 6) = 355.66°

6. HSL
```
hsl(355.66 91.57% 32.55%)
```
