Step-by-step math

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

1. RGB ÷ 255
```
R = 0.8667
G = 0.6275
B = 0.8667
```

2. max, min, Δ

max = 0.8667
min = 0.6275
Δ = max − min = 0.2392

3. L
```
L = (max + min) / 2 = 0.7471 = 74.71%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.4729 = 47.29%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.6275 − 0.8667) / 0.2392) mod 6) = 300.00°

6. HSL
```
hsl(300.00 47.29% 74.71%)
```
