Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0196
G = 0.5882
B = 0.4118
```

2. max, min, Δ

max = 0.5882
min = 0.0196
Δ = max − min = 0.5686

3. L
```
L = (max + min) / 2 = 0.3039 = 30.39%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9355 = 93.55%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.4118 − 0.0196) / 0.5686 + 2) = 161.38°

6. HSL
```
hsl(161.38 93.55% 30.39%)
```
