Step-by-step math

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

1. RGB ÷ 255
```
R = 0.3020
G = 0.0902
B = 0.6039
```

2. max, min, Δ

max = 0.6039
min = 0.0902
Δ = max − min = 0.5137

3. L
```
L = (max + min) / 2 = 0.3471 = 34.71%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.7401 = 74.01%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.3020 − 0.0902) / 0.5137 + 4) = 264.73°

6. HSL
```
hsl(264.73 74.01% 34.71%)
```
