Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9176
G = 0.3451
B = 0.0471
```

2. max, min, Δ

max = 0.9176
min = 0.0471
Δ = max − min = 0.8706

3. L
```
L = (max + min) / 2 = 0.4824 = 48.24%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9024 = 90.24%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.3451 − 0.0471) / 0.8706) mod 6) = 20.54°

6. HSL
```
hsl(20.54 90.24% 48.24%)
```
