Whatever your heart desires. If you think your line up needs some blue, go for it. Pink works well, too. Traditionally I’d say for me, red is what I favour because there shouldn’t ever be a time when your current $5 would be in the same table as a $5000. Unless you have some crazy buy-ins for your cash game. Maybe go a different shade. But I’d say forget about traditionalisms and go with what you heart says.
