Step-by-step math

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

1. input
```
H = 294.69°, S = 72.41%, L = 39.80%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.57638
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.52537   (H / 60° = 4.9115, sector 4)

4. m
```
m = L − C / 2 = 0.10981
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.52537, 0.00000, 0.57638)
R = round((0.52537 + 0.10981) × 255) = 162
G = round((0.00000 + 0.10981) × 255) = 28
B = round((0.57638 + 0.10981) × 255) = 175

6. RGB → HEX
```
#A21CAF
```
