How do you predict green vs. yellow as a category?
I'm not a big player, but every so often when I can see all of the answers at once I'll try and go for the reverse rainbow, but I haven't been able to reliably guess which is green and which is yellow (blue and purple I normally accurately guess). Is there some category of answer or way to reliably predict/distinguish whether a category will be yellow or green?
Purple seems like it's often a "_______ word" or some similar type of category, blue just falls in the category of tricker, or more clever or more specific knowledge, but green and yellow both usually seem equally obvious to me so it's pure guesswork on my part to decide which is the "easiest"(ie. yellow) answer.
Is there something I don't know about what type of answer each category holds?
