Step-by-step math

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

1. RGB ÷ 255
```
R = 0.3216
G = 0.3216
B = 0.3608
```

2. max, min, Δ

max = 0.3608
min = 0.3216
Δ = max − min = 0.0392

3. L
```
L = (max + min) / 2 = 0.3412 = 34.12%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.0575 = 5.75%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.3216 − 0.3216) / 0.0392 + 4) = 240.00°

6. HSL
```
hsl(240.00 5.75% 34.12%)
```
