I don't know how the Rwanda Rainbow got started but the seeds are a variety of colors and they are all solid colors. No patterns or markings. I would bet that all the plants in the mix are probably closely related as the colors in them all seem to have that same tone. Seed shape is all the same and sized the same. Every once in awhile there seems to be a variety that naturally produces several seed coat colors.
your picture in the network pages doesn't reflect the above description so i'm a bit confused by this, perhaps you are describing some other bean?
