Step-by-step math

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

1. RGB ÷ 255
```
R = 0.9843
G = 0.1725
B = 0.2118
```

2. max, min, Δ

max = 0.9843
min = 0.1725
Δ = max − min = 0.8118

3. L
```
L = (max + min) / 2 = 0.5784 = 57.84%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.9628 = 96.28%

5. H

max is R → H = 60° × (((G − B) / Δ) mod 6) = 60° × (((0.1725 − 0.2118) / 0.8118) mod 6) = 357.10°

6. HSL
```
hsl(357.10 96.28% 57.84%)
```
