Step-by-step math

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

1. RGB ÷ 255
```
R = 0.3020
G = 0.0078
B = 0.0941
```

2. max, min, Δ

max = 0.3020
min = 0.0078
Δ = max − min = 0.2941

3. L
```
L = (max + min) / 2 = 0.1549 = 15.49%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9494 = 94.94%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.0078 − 0.0941) / 0.2941) mod 6) = 342.40°

6. HSL
```
hsl(342.40 94.94% 15.49%)
```
