I have a card today for the YNS Color Challenge #53. I am also working on a card for the YNS Sketch Challenge too. I plan to post it later. Here is their color inspiration. Just beautiful!
And here is my card...
I didn't use the pale green and the card base is a pale grey. So I think using 4 of the 5 colors works.
Paper: Inchie Arts and scraps
Stamps: YNS Waddles Snow Fun for the sentiment
