Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9608
G = 0.6196
B = 0.0431
```

2. max, min, Δ

max = 0.9608
min = 0.0431
Δ = max − min = 0.9176

3. L
```
L = (max + min) / 2 = 0.5020 = 50.20%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9213 = 92.13%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.6196 − 0.0431) / 0.9176) mod 6) = 37.69°

6. HSL
```
hsl(37.69 92.13% 50.20%)
```
