Step-by-step math

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

1. RGB ÷ 255
```
R = 0.2941
G = 0.3451
B = 0.3569
```

2. max, min, Δ

max = 0.3569
min = 0.2941
Δ = max − min = 0.0627

3. L
```
L = (max + min) / 2 = 0.3255 = 32.55%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.0964 = 9.64%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.2941 − 0.3451) / 0.0627 + 4) = 191.25°

6. HSL
```
hsl(191.25 9.64% 32.55%)
```
