I created this card for the CST challenge this week which was use black and white with splash of color.
I started with a black card and added a white embossed layer (Cuttlebug - Floral Fantasy) trimmed to just a bit smaller than the card. Then I cut a die with the Sizzix Flourish in black and cut again the hearts in hot pink. I thought it worked well with the hearts and flourishes on the embossed layer. I glued it down and added my hot pink hearts. It was for someone having a birthday so I added a stamped greeting in hot pink and smudged the edge with a black ink pad.
