Step-by-step math

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

1. RGB ÷ 255
```
R = 0.4039
G = 0.4706
B = 0.4863
```

2. max, min, Δ

max = 0.4863
min = 0.4039
Δ = max − min = 0.0824

3. L
```
L = (max + min) / 2 = 0.4451 = 44.51%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.0925 = 9.25%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.4039 − 0.4706) / 0.0824 + 4) = 191.43°

6. HSL
```
hsl(191.43 9.25% 44.51%)
```
