ok upon comparing the old version with new i can see nothing wrong with the old tool background as well as the resins, thread, cloth, dyes, animal carcases, etc etc etc all looked and worked fine so why change.
problem was only with silk and most may be able to live with this change if it was only the silks changed as was the original complaint.
so my opinion would be change everything but silks back and leave only silks black and maybe antialiasing may look better too or better yet would be my opinion of option B as above and only for silks change everything else back
thanks
oh but by the way i do like the black background for bones thats nice
