Step-by-step math

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

1. RGB ÷ 255
```
R = 0.8784
G = 1.0000
B = 1.0000
```

2. max, min, Δ

max = 1.0000
min = 0.8784
Δ = max − min = 0.1216

3. L
```
L = (max + min) / 2 = 0.9392 = 93.92%
```

4. S

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

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((1.0000 − 0.8784) / 0.1216 + 2) = 180.00°

6. HSL
```
hsl(180.00 100.00% 93.92%)
```
