I like your idea computersmith, However. My apps are tailored for not only millennials, but a large majority are Gen X, and even older. So the reason why I wanted my icons to stand out without "doing anything extra" is so it comes clearly to them.
My apps are targetted for the not so smart or experienced mobile users. Basically, I am writing apps for "old people"
However, I do have other apps for different things I think they would work great on. Such as my inventory system that I am slowly building (taking forever)
