Analogous color challenge

Here's a card I made for Heidi's color challenge.
I wet a piece of watercolor paper pretty liberally and used a watercolor cake set to create the background. Once dry, I stamped my images in archival jet black ink and adhered it to a base. It's an odd shaped card but fits in a business size envelope.
Stamps are from inkadinkado and sentiment is Stampabilities. I messed up the sentiment a bit. I need to find my black marker to fix it.
