So if I have dark hair, is there a way to highlight it without first bleaching it?

This is just a thought, but I’ve been considering dying or just highlighting my hair a dark maroon-y red. Nothing outrageous just something fun and different. But, I have dark brown hair. And I don’t know much about hair dye. Preferring not to pay for a professional to do it, if I did it myself, is it possible? I am not going to do it if I have to bleach my hair. No thank you. But if it’s possible to do it without bleaching, I may give it a whirl. So, would it work? Or not show up at all, if it’s a color that is lighter than my current color?
