Step-by-step math

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

1. RGB ÷ 255
```
R = 0.2902
G = 0.0157
B = 0.3059
```

2. max, min, Δ

max = 0.3059
min = 0.0157
Δ = max − min = 0.2902

3. L
```
L = (max + min) / 2 = 0.1608 = 16.08%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9024 = 90.24%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.2902 − 0.0157) / 0.2902 + 4) = 296.76°

6. HSL
```
hsl(296.76 90.24% 16.08%)
```
