Sometimes it is decided that items should not be released in certain Painted colors. This is often because the default color is similar to a Painted color, or the new Painted item looks too much like another Painted item.
We do our best to catch all of these before release. If it is decided that a Painted item needs to be changed, we try to make it right by replacing that item with a different item paint color. This is what happened when we swapped out Crimson-Painted Peppermint Wheels.
