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 = 0.7804
```

2. max, min, Δ

max = 0.9961
min = 0.7804
Δ = max − min = 0.2157

3. L
```
L = (max + min) / 2 = 0.8882 = 88.82%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9649 = 96.49%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.9529 − 0.7804) / 0.2157) mod 6) = 48.00°

6. HSL
```
hsl(48.00 96.49% 88.82%)
```
