Step-by-step math

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

1. input
```
H = 186.71°, S = 97.70%, L = 65.88%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.66670
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.59214   (H / 60° = 3.1118, sector 3)

4. m
```
m = L − C / 2 = 0.32545
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.59214, 0.66670)
R = round((0.00000 + 0.32545) × 255) = 83
G = round((0.59214 + 0.32545) × 255) = 234
B = round((0.66670 + 0.32545) × 255) = 253

6. RGB → HEX
```
#53EAFD
```
