1. Easiest thing you can do is open the flare.png file up in Photoshop or GIMP.
2. Make a new layer and change the new layer type to Overlay, the drop down menu should be next to the opacity menu.
3. Grab a paintbrush and select the colour blue, make sure it's rather dark otherwise it will turn green (don't worry it will turn out a bright blue in-game).
4. Colour the whole layer in, it should change the fire image from orange to dark blue without changing the black background colour.
5. Save the image as it is, same name so it replaces the old one (unless you want to keep the original orange fire, if that's the case you will have to do some name changes in the .particle and .material file)
6. Open up Feralheart and go to Object Maker >> Effect Maker >> Particle and type in
Fire/Campfire then click Add New and the flame should be blue.
Hope this helps
