Any shade of blues, lilacs, white or light grey. Royal blue is good on one accent wall.
Cream is 'neutral' so anything goes! I like terracotta with cream though that is a personal thing.
A pattern with both colours might work, cream goes with anything and if you want to check out other colours that might match use a Paint Colour Chart to see what shade lies between burgundy and brown - if you like that shade go look for a match.
