I also have used butter cream and it is a nice soft yellow. If you have access to Backyard Mosaics by C. Sheerin, it's used quite a bit. She's also paints over it quite a bit too. You can see it on the retro dining table (pg 57) and a birdfeeder (pb 124). However, I think it looks more tan than it is on the table and more white on the feeder.
