A hyper inteligent collective of ducks has made contact with you. They have a deal for you. You can either have free lunch for the rest of your life as long as it's seafood based, on the condition that you never wear any blue clothes ever again.

If you accept the free seafood, you can pay money for for non-seafood based food at the current food price. Blue is defined as any colour where it's RGB value is highest by double in Blue over Red and Green (i.e, 20B, 10R, 10G is Blue, 10B, 10R, 10G is not)
