Step-by-step math

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

1. input
```
H = 229.57°, S = 100.00%, L = 81.96%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.36080
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.06272   (H / 60° = 3.8262, sector 3)

4. m
```
m = L − C / 2 = 0.63920
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.06272, 0.36080)
R = round((0.00000 + 0.63920) × 255) = 163
G = round((0.06272 + 0.63920) × 255) = 179
B = round((0.36080 + 0.63920) × 255) = 255

6. RGB → HEX
```
#A3B3FF
```
