Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6353
G = 0.9569
B = 0.9922
```

2. max, min, Δ

max = 0.9922
min = 0.6353
Δ = max − min = 0.3569

3. L
```
L = (max + min) / 2 = 0.8137 = 81.37%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9579 = 95.79%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.6353 − 0.9569) / 0.3569 + 4) = 185.93°

6. HSL
```
hsl(185.93 95.79% 81.37%)
```
