Click or tap the icon near the upper right corner of the dice box, and choose from the list of themes to color the dice. There are four themes available. Choose the 'rainbow' theme for multiple dice colors if you need to distinguish dice for the purpose of a roll, a game, or really, just for fun. The rainbow theme is my favorite! All dice are themed except for Coins and Bones.
Bones dice look nicer and rotate around the shortest instead of the longest axis. Many bugs were fixed for dice rendering and animation.
