Step-by-step math

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

1. RGB ÷ 255
```
R = 0.0000
G = 0.4784
B = 0.3333
```

2. max, min, Δ

max = 0.4784
min = 0.0000
Δ = max − min = 0.4784

3. L
```
L = (max + min) / 2 = 0.2392 = 23.92%
```

4. S

S = Δ / (1 − |2L − 1|) = 1.0000 = 100.00%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.3333 − 0.0000) / 0.4784 + 2) = 161.80°

6. HSL
```
hsl(161.80 100.00% 23.92%)
```
