Step-by-step math

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

1. input
```
H = 52.76°, S = 98.31%, L = 76.86%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.45498
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.40008   (H / 60° = 0.8793, sector 0)

4. m
```
m = L − C / 2 = 0.54111
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.45498, 0.40008, 0.00000)
R = round((0.45498 + 0.54111) × 255) = 254
G = round((0.40008 + 0.54111) × 255) = 240
B = round((0.00000 + 0.54111) × 255) = 138

6. RGB → HEX
```
#FEF08A
```
