Step-by-step math

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

1. RGB ÷ 255
```
R = 0.1333
G = 0.1608
B = 0.1686
```

2. max, min, Δ

max = 0.1686
min = 0.1333
Δ = max − min = 0.0353

3. L
```
L = (max + min) / 2 = 0.1510 = 15.10%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.1169 = 11.69%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.1333 − 0.1608) / 0.0353 + 4) = 193.33°

6. HSL
```
hsl(193.33 11.69% 15.10%)
```
