Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9255
G = 0.9882
B = 0.7961
```

2. max, min, Δ

max = 0.9882
min = 0.7961
Δ = max − min = 0.1922

3. L
```
L = (max + min) / 2 = 0.8922 = 89.22%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8909 = 89.09%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.7961 − 0.9255) / 0.1922 + 2) = 79.59°

6. HSL
```
hsl(79.59 89.09% 89.22%)
```
