ArcPro loads point data using a pastel color palette. How do I change the default color palette to bolder colors when adding new data to a map project?
Never tried it, but do you have a favorites? or have you tried saving a style? The favorites are supposed to be available across projects. I am not sure that it would stop the pastel showing as the first choice, but it might solve the scrolling/searching thing
