purple , represents the grapes on the coat of arm , but also is unique (i have seen flags of connecticut with a purple background instead of the blue one , so that also ) , a defining feature of the original connecticut flag yellow -white -yellow , this is from the emblem where it says "qui translulit sustinet " and i think it looks well and kinda makes it unique , with the only thing something similar to it being that of uzbekistan blue , represents the Connecticut river
