Hi! I'm newly engaged and in the beginning processes of planning

We are planning a late fall wedding, and would like to have a color scheme that incorporates burnt orange, deep red, golden yellow, cream, and dark brown. First of all, is that too many colors!? Secondly, I'm having trouble deciding what colors our wedding parties should wear. I think I'd like my girls to wear deep red, but can't envision the guys in dark brown without it looking out dated or weird. Can they wear black and it still work if our reception has brown incorporated? Help me please haha I'm a mess!
they say we're young, and we don't know. we won't find out until we grow. well i don't know if all that's true, cause you got me, and baby i got you...
