Step-by-step math

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

1. RGB ÷ 255
```
R = 0.5765
G = 0.2000
B = 0.9176
```

2. max, min, Δ

max = 0.9176
min = 0.2000
Δ = max − min = 0.7176

3. L
```
L = (max + min) / 2 = 0.5588 = 55.88%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8133 = 81.33%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.5765 − 0.2000) / 0.7176 + 4) = 271.48°

6. HSL
```
hsl(271.48 81.33% 55.88%)
```
