Step-by-step math

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

1. RGB ÷ 255
```
R = 0.4039
G = 0.9098
B = 0.9765
```

2. max, min, Δ

max = 0.9765
min = 0.4039
Δ = max − min = 0.5725

3. L
```
L = (max + min) / 2 = 0.6902 = 69.02%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9241 = 92.41%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.4039 − 0.9098) / 0.5725 + 4) = 186.99°

6. HSL
```
hsl(186.99 92.41% 69.02%)
```
