Step-by-step math

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

1. RGB ÷ 255
```
R = 0.4902
G = 0.8275
B = 0.9882
```

2. max, min, Δ

max = 0.9882
min = 0.4902
Δ = max − min = 0.4980

3. L
```
L = (max + min) / 2 = 0.7392 = 73.92%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9549 = 95.49%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.4902 − 0.8275) / 0.4980 + 4) = 199.37°

6. HSL
```
hsl(199.37 95.49% 73.92%)
```
