Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9961
G = 0.9490
B = 0.9490
```

2. max, min, Δ

max = 0.9961
min = 0.9490
Δ = max − min = 0.0471

3. L
```
L = (max + min) / 2 = 0.9725 = 97.25%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8571 = 85.71%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.9490 − 0.9490) / 0.0471) mod 6) = 0.00°

6. HSL
```
hsl(0.00 85.71% 97.25%)
```
