I thought the color challenge from Always Playing with Paper  Color Challenge #64 posted on the blog was a great combination of colors.  I used one of my favorite Penny Black stamps to create a card using  blue, navy blue, lime and gray. I colored the stamped image with Tombow markers, added some accent torn paper accents.  The word tag was added using May Arts twine which is one of my go to accents.  Might try this color combo on another project.
