Each VoxyAsset has its own ColorPalette, the toolkit will keep track of the last selected color in all VoxyAssets.
Each color has a color index and a color value, so you can paint Voxels with for example red, and later just change red color to change the color of all red Voxels.

Tooltips will give you the overall functionality of each tool and how it will work with different keyboard shortcuts.
