Coloured brake fluid

[Catfish]

I want to try using a coloured brake fluid to make flushes foolproof. Does anyone know which brands of
DOT 4 fluid are coloured? ATE Blue looks good, but I can't find a seller in Oz.

Any advice appreciated.

Why do you need it to be coloured? Don't understand what's wrong with the good old way of doing it!
