Food and waste is very hard to distinguish for people with colorblindness

[MaPePeR]

It's very hard to distinguish the food and waste circles for me (and probably a lot of other people). It would be great, if you could use some other color combination that is less prone to this problem. (red + blue?)
Or use different shapes to eliminate the problem altogether. (Circles and empty circles? Stars?)

i like the sound of empty circles. it would make sense too, representing their "used" state.

@Moth-Tolias I made the particles have an outline and waste particles are filled with white, but the outline thickness jumps up and back down every time food is digested

Update: I've fixed the outline jittering problem. How do I make a pull request?

@drherobrine You should fork this repo, which is like a personal copy that goes on your own account instead of Cary's. Here's more info on forks. Either use the web interface on that forked repo or clone it to your local machine to update the changed files. This would be mostly just copy and paste on individual files since you've already made the changes. Then follow this guide to make the pull request back to this repo.

Oops just saw your pull request :) looks like you've got it taken care of.
