ehhh, i can't see a picture, but i think i know what you mean... head over to the editors' depot and grap a fire script, then change the color of the fire and - if required - the condition of its activation.
as it will be certainly done by using the drop command, search for vektorboson's tutorial on this command. -- i can't find it atm, is homepage seems to be down. let me know if i shall send it to you.
if you have any probs, just post here right away
