Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0235
G = 0.3725
B = 0.2745
```

2. max, min, Δ

max = 0.3725
min = 0.0235
Δ = max − min = 0.3490

3. L
```
L = (max + min) / 2 = 0.1980 = 19.80%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8812 = 88.12%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.2745 − 0.0235) / 0.3490 + 2) = 163.15°

6. HSL
```
hsl(163.15 88.12% 19.80%)
```
