Beast Snagga Army Help

Hello Guys, So I really want to color my orks in a beast Snagga style which is white armor with yellow highlights like, and I was thinking about what to do with the bigger characters like ghazkull etc. Would it look better to leave his armor black and do the details in yellow or do the entire armor white and then the yellow details. I don't know if it would look bad to mix big black characters with the smaller white units if I go with the black design. Any Tipps are appreciated 👍🏻.
