Create Colorblind Friendly Homepage

A kollegue of mine was born with colorblindness. He struggles to differenciate between red and green. Quite often he tendet to criticise my homepages and app-layouts that he couldn't see the difference between an green status point and red error status point. After studying this matter, how to make layouts more user friendly I discovered several pages, where colors can be compared whether they are distiguishable or not: (e.g. https://snook.ca/technical/colour_contrast/colour.html#fg=00FF00,bg=E43333) A study reveald that 8% of men tend to have this disability: http://www.colourblindawareness.org/colour-blindness/ therfore I'd really consider, to design UI in a color friendly way.
