I was kidding. It wasn't meant offensively. But yeah, the color blindness is a serious issue. In fact green/red can be used together and distinguished well, but it is important to choose the right hue. Yellowish green (e.g. grasshopper like) is okay, sometimes confused with orange or yellow itself if there's too much of it. The pine greyish green is okay as well. Just saying. Maybe it will help a little. Thinking about things you didnn't realize before.
