Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6235
G = 0.1765
B = 0.0000
```

2. max, min, Δ

max = 0.6235
min = 0.0000
Δ = max − min = 0.6235

3. L
```
L = (max + min) / 2 = 0.3118 = 31.18%
```

4. S

S = Δ / (1 − |2L − 1|) = 1.0000 = 100.00%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.1765 − 0.0000) / 0.6235) mod 6) = 16.98°

6. HSL
```
hsl(16.98 100.00% 31.18%)
```
