Does colors are supported by Step format?

Here a volume created by boolean difference in this crazzy free SolveSpace!
http://solvespace.com/index.pl

(the "not yet save" was a snapshot before my save try! :)



Here I have imported the volume from this Crazzy Solvespace inside Moi
But seems there is no color in Moi
The orange follow colors are added by me, original file imported shown only the default color of Moi!



Here the STP file "colored" from SolveSpace
