Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9882
G = 0.6471
B = 0.6471
```

2. max, min, Δ

max = 0.9882
min = 0.6471
Δ = max − min = 0.3412

3. L
```
L = (max + min) / 2 = 0.8176 = 81.76%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9355 = 93.55%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.6471 − 0.6471) / 0.3412) mod 6) = 0.00°

6. HSL
```
hsl(0.00 93.55% 81.76%)
```
