Projecting outside: colours? Answered

Is there a way to get colours to be more contrasted so that they can be seen more clearly? I want to take this: https://www.instructables.com/id/PROJECTION-BOMBING/ and turn it into this: http://www.gregbernstein.tv/walmartwatch/

Also, is there a way to increase the lumens of a projector by changing the bulb or something? I have a feeling my projector isn't bright enough to project outside. I was thinking of using this: https://www.instructables.com/id/Halogen-Work-Light-Projector-Mod/
Would that be bright enough for outdoors projecting or is there another cheap alternative?
