Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9961
G = 0.9529
B = 0.7765
```

2. max, min, Δ

max = 0.9961
min = 0.7765
Δ = max − min = 0.2196

3. L
```
L = (max + min) / 2 = 0.8863 = 88.63%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9655 = 96.55%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.9529 − 0.7765) / 0.2196) mod 6) = 48.21°

6. HSL
```
hsl(48.21 96.55% 88.63%)
```
