Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0196
G = 0.8745
B = 0.4471
```

2. max, min, Δ

max = 0.8745
min = 0.0196
Δ = max − min = 0.8549

3. L
```
L = (max + min) / 2 = 0.4471 = 44.71%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9561 = 95.61%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.4471 − 0.0196) / 0.8549 + 2) = 150.00°

6. HSL
```
hsl(150.00 95.61% 44.71%)
```
