in viewport colors looks normal, but after rendering the colors look weird, why? How to solve this problem ?

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:

Thank you very much, B.Y.O.B, for your very quick and clear answer

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 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???"

thank you so much again!

thank you so much again!

thank you so much again!

if you see a duplicate message, I tried to add a picture but for some reason went only a test, I apologize, and will try again to add the picture here

I couldn't add pictures, there's an error, okay, I'll stop trying.
