Propane gas fire

Hello.
I’m doing my first steps in Embergen and it’s feels amazing.
I’m trying to create a fire from propane gas burner:

The only thing I managed to create is a pretty simple fire like this:

The problem is the bottom part where the gas comes from tube holes. It ignites and become blue, and only then it creates a regular fire like shown above.
Do you have any idea of how to achieve this bottom part look correctly? I tried gradient remapping but couldn’t get desired results.

Thank you in advance.

Hey sorry for the delay in response here, I would think that using the gradient is the correct way to go and you seem to be pretty close with the screenshot you’ve provided. If you send over your embergen file I can see if i can improve on it
