I am neither from development nor product definition, but Technical Support. However, my elaborated guess is that there are no plans in near future.
This is because applying striped colors to surfaces is quite tricky (in comparison to keeping surfaces monochromous) and needs some programming intelligence to follow the routing appropriately (usually when wrapping textures on surfaces in Creo, the user has to provide the extra intelligence needed to do it appropriately).
Considering that this special coloring is only "cosmetic", I assume that resources are rather put into other functionality enhancements.
But you may check for an existing product idea (use the Search above and then change the "What" to product Ideas) and start a new one (from the Support page), if there is none existing.
