A psychology research says that blue and red combination is hard on eyes
What is it about red
and blue? — When lines (or
letters) of different colors are projected or printed, the depths of the lines
may appear to be different; lines of one color may “jump out” while lines of
another color are recessed. This effect is called Chromostereopsis. This effect
is strongest with red and blue, but it can also happen with other colors (for
example, red and green).
So what? – In addition to causing a depth effect, chromostereopsis can also be annoying and hard on the eyes. It is fatiguing. Although there are different theories as to why your eyes react to these color combinations in the way that they do, the important thing to remember is that they do.

What should you do about it? – If you are a visual or web designer make
sure that you are not using red and blue together in this way. I still find web
sites that have this color combination.
