Whats something unique i could do with my hair?

so i have dark brown hair now with blonde and red highlights and i had that in the past for about 3 years and i loved it but i got tired of it so then i dyed my hair all dark brown and that was too dark for me then i dyed my hair a dark burgundy color with some black peek a boos and i liked that but then i dyed it again to dark brown, blonde and red.... and now im just getting tired of that again.... i want something different and unique i can do with my hair but not too crazy.... like no rainbow colors or scene hair or anything like that... just something fun and different :) i was thinking about going all blonde on top with burgundy underneath but i thought that might fry my hair and then now im thinking all burgundy again with maybe a couple silver highlights.... but idk how long the silver would be able to stay in for.... so im looking for any other ideas... please help? thanks (:
