Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0431
G = 0.3098
B = 0.2902
```

2. max, min, Δ

max = 0.3098
min = 0.0431
Δ = max − min = 0.2667

3. L
```
L = (max + min) / 2 = 0.1765 = 17.65%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.7556 = 75.56%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.2902 − 0.0431) / 0.2667 + 2) = 175.59°

6. HSL
```
hsl(175.59 75.56% 17.65%)
```
