Step-by-step math

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

1. RGB ÷ 255
```
R = 0.6784
G = 0.2745
B = 1.0000
```

2. max, min, Δ

max = 1.0000
min = 0.2745
Δ = max − min = 0.7255

3. L
```
L = (max + min) / 2 = 0.6373 = 63.73%
```

4. S

S = Δ / (1 − |2L − 1|) = 1.0000 = 100.00%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.6784 − 0.2745) / 0.7255 + 4) = 273.41°

6. HSL
```
hsl(273.41 100.00% 63.73%)
```
