Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6353
G = 0.1098
B = 0.6863
```

2. max, min, Δ

max = 0.6863
min = 0.1098
Δ = max − min = 0.5765

3. L
```
L = (max + min) / 2 = 0.3980 = 39.80%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.7241 = 72.41%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.6353 − 0.1098) / 0.5765 + 4) = 294.69°

6. HSL
```
hsl(294.69 72.41% 39.80%)
```
