Step-by-step math

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

1. input
```
H = 343.72°, S = 100.00%, L = 39.02%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.78040
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.21175   (H / 60° = 5.7287, sector 5)

4. m
```
m = L − C / 2 = 0.00000
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.78040, 0.00000, 0.21175)
R = round((0.78040 + 0.00000) × 255) = 199
G = round((0.00000 + 0.00000) × 255) = 0
B = round((0.21175 + 0.00000) × 255) = 54

6. RGB → HEX
```
#C70036
```
