Redshift. There are many realities. Not dimensions as has become standard sci fi fare. Realites are fixed by a mathematical sub/superstructure. Please accept this on blind faith. Now given that the set of real numbers is infinite, it follows from this simple fact that there are an infinite number of realities. I know, I know, but it does. The set of real numbers includes the set of all integers, while the converse obviously is false. (The converse of truth is falsity, except when it is true.) Redshift corresponds to the set of integers while the reality most of us take for granted is the set of real numbers.
And remember Dialectic Method #3: If you feel your theory crumbling, attack first principles and question terms.
Furthermore, color is the gateway of mathematics and hence reality. If you understand this on an emotional or hyperlogical level, you can use this knowledge to manipulate what is perceived as real. Mathematics is Logic, while color is the emotion which underlies all logical systems. I didn't make this up of course, but I am dabbling in certain Redshift Experiments, the results of which I may detail at a later date.
Oh, the pain! The Pain! My kingdom for a grand unification theory.
