HELP!! Need Red "paint" for marshmallow fondant quick

I am making a guitar cake and covering it in MMF.  I want to make it red, but it is really difficult to not get pink when adding red coloring to white fondant.  I know that I can mix red gel color with an extract with alcohol to paint the red color on the fondant.  I like to use almond, but I think for the amount I need it will add way too much extra flavor.  Is there another neutral ingredient that i can add to increase the volume without dramatically changing the taste?  I thought maybe water or light corn syrup.  My kitchen is stocked with the at-home cook basics. I really dont want to make a special trip to the store, so "normal" readily ingredients are preferred.   Any advice would be greatly appreciated!!!

 

Well, I couldnt find my paintbrush and I ended up using a paper towel to "brush on" an almond extract and gel food coloring mixture.  It was not super easy but it got the job done.  I had a real tough time covering the guitar with fondant.  How do you get into those little cracks? It was a bit of a disaster as far as that went.  Luckily this is for a friend and not any paying customer   It was still cute overall....
