i have been recently on fluid preset so to get ideas about how to set a fluid fire, but there was
a problem that i couldnt get it and that there are two colors in the incandesence that are put
automaticly without manual selection to them, as you can see at the attached file there arent
any circles above the yellow and red colors which indicate that i chose those two colors, i hope
i explained my problem well.

Hey, had the same problem bout a year or so ago. The value of the color (hue, saturation, value) is blown out to 20. gives it that nice faded edge, works on any ramp. set it to 1 and see how crappy it looks. I had to rebuild that whole scene one number at a time to find that... some people have found this tutorial helpful, http://zgrachan.com/pages/fireTut.htm. wrote that right after i grajiated.

Incandescence from a fire can be much brighter than would be white on the current camera exposure. There is no max, just a light can have any intensity. When you make a very bright orange-red( that is not 100% saturated) when the intensity interpolates to black it goes through white-yellow-orange-red-black, just like a real flame does. This is because the rgb each saturates at a different point. When it is brighter than white it will punch through opaque clouds, as well as illuminate brightly even when the density is thin and transparent, making it glowy( like flames ).

Thus sometimes it makes sense to use color values outside the 0-1 range.
