Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6588
G = 0.6353
B = 0.6196
```

2. max, min, Δ

max = 0.6588
min = 0.6196
Δ = max − min = 0.0392

3. L
```
L = (max + min) / 2 = 0.6392 = 63.92%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.0543 = 5.43%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.6353 − 0.6196) / 0.0392) mod 6) = 24.00°

6. HSL
```
hsl(24.00 5.43% 63.92%)
```
