I guess I've never tried white without the big black pebbles? May very well wash all Marbles out. Mine have colored up quite a bit with a change in lighting. Substrate staying the same. Seems like you can get changes with either light or subtrate.
What exactly are you using for lighting?
I added orange sand to my pup tank and it's taken several months but I can say they are darkening... Light remaining constant.
I've seen really good results with tan/natural as well, but personally never tried it very long.
