Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9333
G = 0.9490
B = 1.0000
```

2. max, min, Δ

max = 1.0000
min = 0.9333
Δ = max − min = 0.0667

3. L
```
L = (max + min) / 2 = 0.9667 = 96.67%
```

4. S

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

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.9333 − 0.9490) / 0.0667 + 4) = 225.88°

6. HSL
```
hsl(225.88 100.00% 96.67%)
```
