Step-by-step math

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

1. RGB ÷ 255
```
R = 1.0000
G = 0.1255
B = 0.3373
```

2. max, min, Δ

max = 1.0000
min = 0.1255
Δ = max − min = 0.8745

3. L
```
L = (max + min) / 2 = 0.5627 = 56.27%
```

4. S

S = Δ / (1 − |2L − 1|) = 1.0000 = 100.00%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.1255 − 0.3373) / 0.8745) mod 6) = 345.47°

6. HSL
```
hsl(345.47 100.00% 56.27%)
```
