Step-by-step math

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

1. input
```
H = 191.43°, S = 9.25%, L = 44.51%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.08234
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.06666   (H / 60° = 3.1905, sector 3)

4. m
```
m = L − C / 2 = 0.40393
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.00000, 0.06666, 0.08234)
R = round((0.00000 + 0.40393) × 255) = 103
G = round((0.06666 + 0.40393) × 255) = 120
B = round((0.08234 + 0.40393) × 255) = 124

6. RGB → HEX
```
#67787C
