Step-by-step math

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

1. input
```
H = 199.37°, S = 95.49%, L = 73.92%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.49808
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.33728   (H / 60° = 3.3228, sector 3)

4. m
```
m = L − C / 2 = 0.49016
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.33728, 0.49808)
R = round((0.00000 + 0.49016) × 255) = 125
G = round((0.33728 + 0.49016) × 255) = 211
B = round((0.49808 + 0.49016) × 255) = 252

6. RGB → HEX
```
#7DD3FC
```
