red green is bad because of colour blindness

  All colors are potentially problematic. https://en.wikipedia.org/wiki/Color_blindness#Types https://en.wikipedia.org/wiki/Color_blindness#Types

    I once read, contrast is the key. All colors are problematic, but if you get your contrast high enough, this doesn't matter.

      A more reliable and helpful approach is to make sure that colors meant to convey information are augmented by some other indicator (symbols/shapes, text labels, line styles, etc.) whenever possible. In addition to avoiding colorblindness issues, this makes the difference easier to recognize in general. It also helps accommodate non-ideal viewing conditions such as a washed-out display, coordinating between displays that are calibrated differently, monochrome print/e-ink, and so on.
