I want to dye my hair dark chocolaty brown black i have freckles will it look strange?

i want to dye my hair with 'John Frieda Foam Colour Deep Natural Brown 3N' which is a very dark chocolate brown - black but i have freckles all over my face and a yellow red complection although i do wear alot of foundation to cover them up they are still very noticable. i have naturally black eyebrows so i presumed it would look ok, what do you think?
