Step-by-step math

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

1. RGB ÷ 255
```
R = 0.4275
G = 0.1569
B = 0.8510
```

2. max, min, Δ

max = 0.8510
min = 0.1569
Δ = max − min = 0.6941

3. L
```
L = (max + min) / 2 = 0.5039 = 50.39%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.6996 = 69.96%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.4275 − 0.1569) / 0.6941 + 4) = 263.39°

6. HSL
```
hsl(263.39 69.96% 50.39%)
```
