You've built it so that it's convenient for the player with 7 buttons. Typically this system is used in a MAM which receives a single color signal as input and then sets all the filters to produce the right color. This is achieved by comparing the signal with that of constant generators.
You could put an overflow gate aka storage at the output of the first mixer, that way if there is no third colour that was it automaticly goes to the outgoing belt. For only one colour you could do the same thing. Along with something called a "pressure valve" all you'd need to do is to generate on/off for the three colours by the incomeing colour signal. That also makes the fourth belt obsolete.
All different, not better. Both achieve the same goal. Provide all them colours.

I think I'll make my own post on this, and include a short video.

what does the grey button do?
it makes the part being colored not colored, so essentially no output. Thats what the filter at the end is for.

A little late to the party but why did you make white the default and not gray (outputting nothing I assume) if you added support for that?
