Values are shown at full precision, so converting back gives exactly #0c090c. The rounded form is what you normally paste into CSS.

Step-by-step math

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

1. input
```
H = 300.00°, S = 14.29%, L = 4.12%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.01177
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.01177   (H / 60° = 5.0000, sector 5)

4. m
```
m = L − C / 2 = 0.03531
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.01177, 0.00000, 0.01177)
R = round((0.01177 + 0.03531) × 255) = 12
G = round((0.00000 + 0.03531) × 255) = 9
B = round((0.01177 + 0.03531) × 255) = 12

6. RGB → HEX
```
#0C090C
```
