Step-by-step math

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

1. RGB ÷ 255
```
R = 0.7333
G = 0.9569
B = 0.3176
```

2. max, min, Δ

max = 0.9569
min = 0.3176
Δ = max − min = 0.6392

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

4. S

S = Δ / (1 − |2L − 1|) = 0.8811 = 88.11%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.3176 − 0.7333) / 0.6392 + 2) = 80.98°

6. HSL
```
hsl(80.98 88.11% 63.73%)
```
