Step-by-step math

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

1. RGB ÷ 255
```
R = 0.2824
G = 0.8196
B = 0.8000
```

2. max, min, Δ

max = 0.8196
min = 0.2824
Δ = max − min = 0.5373

3. L
```
L = (max + min) / 2 = 0.5510 = 55.10%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.5983 = 59.83%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.8000 − 0.2824) / 0.5373 + 2) = 177.81°

6. HSL
```
hsl(177.81 59.83% 55.10%)
```
