While considering entering the Instructables Colors of the Rainbow Contest, I noticed there was a special prize of a 3D printer for entries that were good examples of each of the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet, and another for the best "rainbow" entry. Wanting to maximize my chances at one of these, I decided to figure out which of these colors were least used among the entries at the time (June 4, 2018), then come up with an Instructable based around that color. I scrolled through the entries a few times, but found it hard to keep track. It was obvious "rainbow" was the most popular color, but less obvious what the least popular was. So I made a Rainbow Tally Counter to help me keep track.
Step 1: Code It!
You'll see that we set up 8 DIVs (boxes) with background colors corresponding to one of the 8 categories (rainbow is denoted by gray, because why not?). Clicking on a box will increase that color's associated counter by one. To reset it, just reload the page.
Step 2: The Tally and Results
I opened 2 windows: one with the contest entries to date, the other with my tally counter. As I scrolled through the entries, I tallied which category I thought each entry would fall into. If it might fall under more than one category, I clicked more than one box.
Green/Yellow: 6 each
So I decided to try to come up with an Instructable featuring orange or violet prominently! Let's see if I can think of one.
