Generally speaking food coloring is water base. And the reason you are flushing the brake system is to rid the bake fluid of the water it has absorbed over time. Brake fluid is pretty much hygroscopic and absorbs water, water lowers the boiling point of brake fluid and allows it to attack the inside of the brake system

I have used the Pentosin Brake fluid which is yellow, but I heard today from a employee that works for a vendor we all know, that 1 (one) drop of food coloring in a liter of brake fluid would not hurt anything. It's quite inert I hear. I questioned it and was told many that race cars do it all the time. I hate the fact that ATE, which is pronounced AH TAE no longer makes the blue fluid. My Nissan pickup is due, and I plan on trying a drop of red food coloring in Prestone's dot 3 fluid.
