Color alphabet

I want to show you a prototype of one of my non-commercial projects. The idea is simple - replace the letters in words with colored squares. It is expected that the human brain spends significantly less time on color recognition than on the definition of a sign, and such a system will increase the speed and simplify the reading process.
As an example, the book “The Problem of Three Bodies” was chosen, the author is Liu Cixin. Gradually, with each page read, the letters in the squares will disappear and by the end of the book there will be no letters at all.
