We will need to use V-Ray's Atmosphere and Self-Illumination Render Elements so we will add these in the Render Elements tab.
Note that you need to set the Simulator's Render Mode to Volumetric in order to get the VRayAtmosphere render element.
For more information about the supported Render Elements visit the V-Ray Render Elements Support page.
After rendering the image we will save it as a multichannel EXR so it will be easier to manage.
The Atmosphere Render Element will give you the Smoke + the illumination produced by the fireFire.
The Self-Illumination Render Element returns the fire Fire only.
You can directly modify the fire Fire using the Self-Illumination pass.
To isolate the smokeSmoke, create a Merge node and connect input A to the Atmosphere pass and input B to the Self-Illumination pass.
Set the operation to Minus and the Self-Illumination pass will be subtracted thus leaving us with the illuminated smoke Smoke only.
You can now Color Correct both the fire Fire and the smoke Smoke separately for more creative control.
Add a Hue Shift node to both passes and change the Hue rotation to 180 which will give a blue tint to the pass.
To lower the Fire Intensity, you can add a Grade node in the Self-Illumination chain and reduce the Gain by 0.5.
You can then Merge the fire Fire back over the smoke Smoke using a Plus operation to get the final result.
