Step-by-step math

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

1. RGB ÷ 255
```
R = 0.4941
G = 0.1333
B = 0.8078
```

2. max, min, Δ

max = 0.8078
min = 0.1333
Δ = max − min = 0.6745

3. L
```
L = (max + min) / 2 = 0.4706 = 47.06%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.7167 = 71.67%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.4941 − 0.1333) / 0.6745 + 4) = 272.09°

6. HSL
```
hsl(272.09 71.67% 47.06%)
```
