Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6902
G = 0.7686
B = 0.8706
```

2. max, min, Δ

max = 0.8706
min = 0.6902
Δ = max − min = 0.1804

3. L
```
L = (max + min) / 2 = 0.7804 = 78.04%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.4107 = 41.07%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.6902 − 0.7686) / 0.1804 + 4) = 213.91°

6. HSL
```
hsl(213.91 41.07% 78.04%)
```
