Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6471
G = 0.7059
B = 0.9882
```

2. max, min, Δ

max = 0.9882
min = 0.6471
Δ = max − min = 0.3412

3. L
```
L = (max + min) / 2 = 0.8176 = 81.76%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9355 = 93.55%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.6471 − 0.7059) / 0.3412 + 4) = 229.66°

6. HSL
```
hsl(229.66 93.55% 81.76%)
```
