Step-by-step math

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

1. RGB ÷ 255
```
R = 0.5765
G = 0.4392
B = 0.8588
```

2. max, min, Δ

max = 0.8588
min = 0.4392
Δ = max − min = 0.4196

3. L
```
L = (max + min) / 2 = 0.6490 = 64.90%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.5978 = 59.78%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.5765 − 0.4392) / 0.4196 + 4) = 259.63°

6. HSL
```
hsl(259.63 59.78% 64.90%)
```
