Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9725
G = 0.4431
B = 0.4431
```

2. max, min, Δ

max = 0.9725
min = 0.4431
Δ = max − min = 0.5294

3. L
```
L = (max + min) / 2 = 0.7078 = 70.78%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9060 = 90.60%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.4431 − 0.4431) / 0.5294) mod 6) = 0.00°

6. HSL
```
hsl(0.00 90.60% 70.78%)
```
