Blacked out with 4 colour deck for cash games and the green for vanilla MTTs, Red for PKO's and Blue for Sit and Gos. I know some people (streamers) also change the colour of the table when they have made the money in an MTT.
Lots of ways you could do it, in the end it just comes down to personal preference and what you find the most visually appealing. Some sites also have after market software you can purchase to further customise your table layouts
GL on the tables no matter what colour you choose!
