I am using the OWH Card Sketch #193 for my card today. For the color I found some inspiration on Dynamic Duos. At first Cajun Craze and Island Indigo seemed like a stretch for me, but then I found a way to combine them that made sense to me.
I used the stamp set By the Tide. I stamped the coral/seaweed with Cajun Craze ink at full strength at the bottom of the Very Vanilla card layer then stamped off twice to create the background. I stamped the fish in Island Indigo twice (stamped off once). I added a Cajun Craze and Island Indigo layer behind the stamping and then attached the whole thing to a Crumb Cake card base.
