You might want to try a product called Zinnzer Bullseye 123. It's a latex primer that will adhere to slippery things like tile. - - - - - No paint, including Zinsser Bullseye 1-2-3, will stick to regular silicone caulk. You can try one of four things, all of which involve removing the old silicone. First, silicone comes in several colors. If the paint color you're using is close to a silicone color, recaulk with colored silicone. There's also clear silicone. That blends in very well and it's hard to see.

It lasts better than silicone does, and you can paint it with latex or oil-based paint.
