It's pretty obvious visually, you take the exclusive disjunct (a^b -> yellow) divide by two (>>1 -> bright yellow) and then add the intersection (a&b -> green)

It's pretty obvious visually, you take the exclusive disjunct (a^b -> yellow) divide by two (>>1 -> bright yellow) and then add the intersection (a&b -> green) you use the full intersection because in the basic method (a+b / 2) they would each add their own half of the intersection. https://imgur.com/PUT4G9Z https://imgur.com/PUT4G9Z
