Step-by-step math

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

1. input
```
H = 273.41°, S = 100.00%, L = 63.73%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.72540
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.40393   (H / 60° = 4.5568, sector 4)

4. m
```
m = L − C / 2 = 0.27460
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.40393, 0.00000, 0.72540)
R = round((0.40393 + 0.27460) × 255) = 173
G = round((0.00000 + 0.27460) × 255) = 70
B = round((0.72540 + 0.27460) × 255) = 255

6. RGB → HEX
```
#AD46FF
```
