Colour scheme #3 contains more earthy tones that look great when separated by the black/charcoal colour. Normally I don’t tend to mix browns with different undertones often but in this case the burgundy-brown mashes in well with the orangey-browns. The brown with a hint of yellow goes well with the olive green colour. The blue-greys make the whole scheme come alive. My advice would be to use more of the neutral colours and the brighter ones as pops of colour. I think less may be more in this case, but it all depends on the quilt or artwork.
As with all colour schemes, mix and match darker and lighter values of each colour shown here.
