Step-by-step math

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

1. input
```
H = 229.66°, S = 93.55%, L = 81.76%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.34127
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.05881   (H / 60° = 3.8277, sector 3)

4. m
```
m = L − C / 2 = 0.64696
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.05881, 0.34127)
R = round((0.00000 + 0.64696) × 255) = 165
G = round((0.05881 + 0.64696) × 255) = 180
B = round((0.34127 + 0.64696) × 255) = 252

6. RGB → HEX
```
#A5B4FC
```
