Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0314
G = 0.1843
B = 0.2863
```

2. max, min, Δ

max = 0.2863
min = 0.0314
Δ = max − min = 0.2549

3. L
```
L = (max + min) / 2 = 0.1588 = 15.88%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8025 = 80.25%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.0314 − 0.1843) / 0.2549 + 4) = 204.00°

6. HSL
```
hsl(204.00 80.25% 15.88%)
```
