Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9412
G = 1.0000
B = 0.9412
```

2. max, min, Δ

max = 1.0000
min = 0.9412
Δ = max − min = 0.0588

3. L
```
L = (max + min) / 2 = 0.9706 = 97.06%
```

4. S

S = Δ / (1 − |2L − 1|) = 1.0000 = 100.00%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.9412 − 0.9412) / 0.0588 + 2) = 120.00°

6. HSL
```
hsl(120.00 100.00% 97.06%)
```
