Step-by-step math

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

1. RGB ÷ 255
```
R = 0.7451
G = 0.0706
B = 0.2353
```

2. max, min, Δ

max = 0.7451
min = 0.0706
Δ = max − min = 0.6745

3. L
```
L = (max + min) / 2 = 0.4078 = 40.78%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8269 = 82.69%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.0706 − 0.2353) / 0.6745) mod 6) = 345.35°

6. HSL
```
hsl(345.35 82.69% 40.78%)
```
