Red and green do cause problems for those with some forms of color vision deficiencies, especially if they have similar levels of lightness and saturation. We see that orange and green are also difficult to distinguish for those with color vision deficiencies. Other combinations may cause problems as well. I recommend using a color vision simulator to make sure that figures are accessible to as large an audience as possible.

Pie charts are rarely the best way to show data and multiple pie charts are even worse.

It shows the data in a more space efficient manner that facilitates comparisons of interest.
