Step-by-step math

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

1. RGB ÷ 255
```
R = 0.8471
G = 0.9765
B = 0.6000
```

2. max, min, Δ

max = 0.9765
min = 0.6000
Δ = max − min = 0.3765

3. L
```
L = (max + min) / 2 = 0.7882 = 78.82%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8889 = 88.89%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.6000 − 0.8471) / 0.3765 + 2) = 80.63°

6. HSL
```
hsl(80.63 88.89% 78.82%)
```
