Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6863
G = 0.9333
B = 0.9333
```

2. max, min, Δ

max = 0.9333
min = 0.6863
Δ = max − min = 0.2471

3. L
```
L = (max + min) / 2 = 0.8098 = 80.98%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.6495 = 64.95%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.9333 − 0.6863) / 0.2471 + 2) = 180.00°

6. HSL
```
hsl(180.00 64.95% 80.98%)
```
