If I may make a suggestion: use yellow and blue as highlighting colors
instead of red and green because about 8% of males ( 0.5% of females) have
some form of red-green color blindness (actually "color perception
deficiency" would be more accurate).  This means that all of us probably
know a few people among our friends and colleagues who are red-green
colorblind. Only about 0.008% have blue-yellow color blindness, so
blue-yellow is a better choice than red-green.
