How credible is the Remenko's two-component color vision theory?
That era produced a lot of very questionable science from Russia; there is no good reason to doubt the three-component color vision theory, and it's also the basis of all RGB TVs and computer monitors. However, I can't read Russian so I don't have any idea what this two-component theory is.

Typical humans have three cone cells, which is the biological origin of having three components for color vision. Colorblind individuals who lack one of the three cones have color discrimination issues consistent with the three component model. I am not aware of any credible research that questions this.

The lack of further study into the theory you refer to probably puts it into the category of "not even wrong" - based on such flawed reasoning or premises that it isn't worth disputing.
