The cube allows one to examine the outer surface of the RGB space; as well as illustrating the relationship between additive and subtractive spaces. In terms of my ideological representation issue, I was able to communicate that the 3-axes used to represent Red, Green, and Blue values could be relabeled to represent the percent of the vote supporting Conservative, Alternative, and Liberal ideologies.
Now I’m sharing, so you can make your own. You’ll need:
- a color printer or access to one.
- some poster board or other heavy (but flexible) art board
- an Xacto knife or other cutting implement.
- a ruler
- a pencil
- glue-stick, or other paper adhesive.
After printing, cut out and trace on to the art board one of the following PDFs (remember to add tabs if using the original PDF):
- Here’s the original PDF;
- and if you want to hide the edges, here’s one with tabs.
Next, you’ll cut out and fold the art board into a cube being sure to tuck the tabs in, so you have a more-or-less smooth external surface.
Then you’ll want to do the same with the color print-out, only this time gluing it to the art board cube you’ve assembled. (Again, remember to tuck any tabs underneath.)
Optionally, you may attempt to cover your creation with a protective covering (this usually doesn’t go as well as one would like — I wrapped mine in packing tape, but it got blisters and a tiny patch of color torn, etc.)
