Color Combination Coding


Callie and Josh


Our task was to create a system for sending messages 600 feet, using technology available before 1800.
Here's Steve, explaining our task.
We used a color combination system with a key to send a selection of thirty critical messages.

Josh is sending a message to me on the other side of the quad.
Josh needs a beer. I am a tiny speck.
