@marcelliino made an amazingly cool color picker here: https://codea.io/talk/discussion/10653/color-changer-glsl-chroma-key
…however it wasn’t super easy to use in other projects. This version has been slightly tweaked so you can easily add this great color picker to your own apps as a dependency. The zip file includes the original project as well as a sample project showing how to use it as a dependency.
