Step-by-step math

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

1. RGB ÷ 255
```
R = 0.5804
G = 0.0000
B = 0.8275
```

2. max, min, Δ

max = 0.8275
min = 0.0000
Δ = max − min = 0.8275

3. L
```
L = (max + min) / 2 = 0.4137 = 41.37%
```

4. S

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

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.5804 − 0.0000) / 0.8275 + 4) = 282.09°

6. HSL
```
hsl(282.09 100.00% 41.37%)
```
