Modular bedframes, blankets etc.

One of the issues I have had when trying to create varied furniture is that beds come in limited colors. The problem I have encountered is that the bedframe's color shifts noticeably when I change the hue of the bed. See the attached image.

I would therefore like to have modular bed parts in a single color, so I can shift blanket hues more easily. It would also be nice to have a few different wrinkle patterns.
