From what I've seen, there is no symbol in all of the groups of symbols which I cannot change the color of. Yet, I can change the color of the symbol if I import the map from ArcPro, as long as I don't change the symbol type, only the shape and size. I was asked to have one feature be labeled as differently colored triangles, and others to be symbolized as other simple shapes. But, I would like to know if there are these simple shapes that I can change the color without having to download the map into ArcPro, and then import back to AGOL.
