Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0863
G = 0.1412
B = 0.3373
```

2. max, min, Δ

max = 0.3373
min = 0.0863
Δ = max − min = 0.2510

3. L
```
L = (max + min) / 2 = 0.2118 = 21.18%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.5926 = 59.26%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.0863 − 0.1412) / 0.2510 + 4) = 226.88°

6. HSL
```
hsl(226.88 59.26% 21.18%)
```
