Step-by-step math

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

1. RGB ÷ 255
```
R = 0.7922
G = 0.8353
B = 0.8863
```

2. max, min, Δ

max = 0.8863
min = 0.7922
Δ = max − min = 0.0941

3. L
```
L = (max + min) / 2 = 0.8392 = 83.92%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.2927 = 29.27%

5. H

max is B → H = 60° × ((R − G) / Δ + 4) = 60° × ((0.7922 − 0.8353) / 0.0941 + 4) = 212.50°

6. HSL
```
hsl(212.50 29.27% 83.92%)
```
