Step-by-step math

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

1. RGB ÷ 255
```
R = 0.7294
G = 0.3333
B = 0.8275
```

2. max, min, Δ

max = 0.8275
min = 0.3333
Δ = max − min = 0.4941

3. L
```
L = (max + min) / 2 = 0.5804 = 58.04%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.5888 = 58.88%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.7294 − 0.3333) / 0.4941 + 4) = 288.10°

6. HSL
```
hsl(288.10 58.88% 58.04%)
```
