Step-by-step math

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

1. RGB ÷ 255
```
R = 0.5412
G = 0.1686
B = 0.8863
```

2. max, min, Δ

max = 0.8863
min = 0.1686
Δ = max − min = 0.7176

3. L
```
L = (max + min) / 2 = 0.5275 = 52.75%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.7593 = 75.93%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.5412 − 0.1686) / 0.7176 + 4) = 271.15°

6. HSL
```
hsl(271.15 75.93% 52.75%)
```
