Step-by-step math

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

1. RGB ÷ 255
```
R = 0.4471
G = 0.0745
B = 0.4706
```

2. max, min, Δ

max = 0.4706
min = 0.0745
Δ = max − min = 0.3961

3. L
```
L = (max + min) / 2 = 0.2725 = 27.25%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.7266 = 72.66%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.4471 − 0.0745) / 0.3961 + 4) = 296.44°

6. HSL
```
hsl(296.44 72.66% 27.25%)
```
