Step-by-step math

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

1. RGB ÷ 255
```
R = 0.2902
G = 0.3333
B = 0.3961
```

2. max, min, Δ

max = 0.3961
min = 0.2902
Δ = max − min = 0.1059

3. L
```
L = (max + min) / 2 = 0.3431 = 34.31%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.1543 = 15.43%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.2902 − 0.3333) / 0.1059 + 4) = 215.56°

6. HSL
```
hsl(215.56 15.43% 34.31%)
```
