Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9765
G = 0.9843
B = 0.9843
```

2. max, min, Δ

max = 0.9843
min = 0.9765
Δ = max − min = 0.0078

3. L
```
L = (max + min) / 2 = 0.9804 = 98.04%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.2000 = 20.00%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.9843 − 0.9765) / 0.0078 + 2) = 180.00°

6. HSL
```
hsl(180.00 20.00% 98.04%)
```
