Is it possible to make fire color darker in Niagara Fluids?

Thank you, and sorry for the late reply. I checked based on your answer, but strangely, I don’t see the “Use Blackbody Curve” option in my editor.
Is there something I need to enable first in order to make the “Use Blackbody Curve” setting visible?

Since I’m Korean, I’m sorry that it’s in korean.. TT
