I think osage looks good with about any medium brown to dark brown wood. Be it walnut, Ipe, shedua..etc.
Bubuinga & chechen, can look very nice with their orangish tones.
White woods can look very nice with osage too..just not my preference.
My favorite combo I seen is bacote and osage.
it's not great looking when "fresh"..but...
Once the osage darkens to it's golden color I find the lighter colored grains in the bacote really compliments the osage and they pull together to make a great combo.
