Step-by-step math

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

1. RGB ÷ 255
```
R = 0.4706
G = 0.4431
B = 0.4235
```

2. max, min, Δ

max = 0.4706
min = 0.4235
Δ = max − min = 0.0471

3. L
```
L = (max + min) / 2 = 0.4471 = 44.71%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.0526 = 5.26%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.4431 − 0.4235) / 0.0471) mod 6) = 25.00°

6. HSL
```
hsl(25.00 5.26% 44.71%)
```
