Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9922
G = 0.8784
B = 0.2784
```

2. max, min, Δ

max = 0.9922
min = 0.2784
Δ = max − min = 0.7137

3. L
```
L = (max + min) / 2 = 0.6353 = 63.53%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9785 = 97.85%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.8784 − 0.2784) / 0.7137) mod 6) = 50.44°

6. HSL
```
hsl(50.44 97.85% 63.53%)
```
