Step-by-step math

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

1. input
```
H = 82.71°, S = 77.97%, L = 55.49%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.69409
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.43138   (H / 60° = 1.3785, sector 1)

4. m
```
m = L − C / 2 = 0.20786
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.43138, 0.69409, 0.00000)
R = round((0.43138 + 0.20786) × 255) = 163
G = round((0.69409 + 0.20786) × 255) = 230
B = round((0.00000 + 0.20786) × 255) = 53

6. RGB → HEX
```
#A3E635
```
