Step-by-step math

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

1. RGB ÷ 255
```
R = 0.5569
G = 0.3176
B = 1.0000
```

2. max, min, Δ

max = 1.0000
min = 0.3176
Δ = max − min = 0.6824

3. L
```
L = (max + min) / 2 = 0.6588 = 65.88%
```

4. S

S = Δ / (1 − |2L − 1|) = 1.0000 = 100.00%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.5569 − 0.3176) / 0.6824 + 4) = 261.03°

6. HSL
```
hsl(261.03 100.00% 65.88%)
```
