You need a slightly more complicated node setup for colored smoke:
viewtopic.php?f=5&t=9&p=2918#p2918
Note that you usually want to drive the smoke color via absorption, not scattering, because it behaves a lot more predictable.
(you might have to play with the absorption depth depending on the size of your smoke sim to get a nice saturated color)

Here's also an example file:

Yes, I roughly understood that in luxcore as in cycles the choice of color for smoke is due to the absorption of color, I tried to do it but my domain became completely white, not just smoke, I did not know that you need to use the math node :o I just didn't understand how I needed to adjust the nodes to make the smoke look normal.

Yes, I saw your video on YouTube with a smoke test, when I tried to make the smoke color, and I could not, I was puzzled for a few minutes and thought, "how did you make the smoke color and it looks normal???" :o :shock: :shock: :lol: :lol:
