Combine protein powder, collagen, almond flour, sweetener, and salt in a food processor.
With the food processor running, stream the water, vanilla, and orange flavor. Process until the batter comes together in a large ball. Add water and dye and then add more water a tablespoon at a time and process well to ensure it is incorporated before adding more if it seems too dry. Gently knead in the chocolate.
Press into an 8×8-inch pan lined with parchment or plastic wrap.
Refrigerate until cool and set, about an hour, slice into 12 bars and wrap individually with parchment paper. Store in the refrigerator until eating as they can spoil. These can be taken for travel and will not melt although they will get quite soft and tacky when warm.
