Step-by-step math

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

1. input
```
H = 207.27°, S = 44.00%, L = 49.02%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.43138
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.23532   (H / 60° = 3.4545, sector 3)

4. m
```
m = L − C / 2 = 0.27451
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.23532, 0.43138)
R = round((0.00000 + 0.27451) × 255) = 70
G = round((0.23532 + 0.27451) × 255) = 130
B = round((0.43138 + 0.27451) × 255) = 180

6. RGB → HEX
```
#4682B4
```
