Step-by-step math

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

1. RGB ÷ 255
```
R = 0.2980
G = 0.0196
B = 0.0980
```

2. max, min, Δ

max = 0.2980
min = 0.0196
Δ = max − min = 0.2784

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

4. S

S = Δ / (1 − |2L − 1|) = 0.8765 = 87.65%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.0196 − 0.0980) / 0.2784) mod 6) = 343.10°

6. HSL
```
hsl(343.10 87.65% 15.88%)
```
