Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9843
G = 0.5725
B = 0.2353
```

2. max, min, Δ

max = 0.9843
min = 0.2353
Δ = max − min = 0.7490

3. L
```
L = (max + min) / 2 = 0.6098 = 60.98%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9598 = 95.98%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.5725 − 0.2353) / 0.7490) mod 6) = 27.02°

6. HSL
```
hsl(27.02 95.98% 60.98%)
```
