I made this fire/hot metal node setup and can't figure out how to change it's natural colours to blue. I tried colourizing the image texture (lava was used) but it didn't work. Also tried using RGB to black and white with the image textures and playing around with hue/saturation, but nothing will change this natural hot metal colour. I would post the node setup, but it was way to big to show in one picture. However, I have posted the .blend.
Thanks
