Colored-Light Art

In our class on Color today, I showed some random art that I had made up while experimenting with using colored light to reveal hidden images.

Since the class seemed to be pretty interested (and since I was asked), I am sharing that here in case anyone wants to try doing it themselves.  The image below explains what I did and shows the examples.  In case you would like to use your phone to create flashing light colors, I have saved the gifs I made in the linked Google drive folder: GIFs RGB Flash
