While I was joking to some extent I will rebut my actions. What you did was an animation, more specifically an effect that cycles colors in a loop inside the star shape. It just happens that in a still frame it would be classified as "pillow-shading", however, the star itself will never be used as such in game, as it would be animated rather.
To actually go out of ones way to shade using "that technique" shows a lack of knowledge. Why would anyone pillow shade? There's no reason to. And again, the animation doesn't apply to those rules, but I already explained that above.
I don't feel there's much use getting too much into this. I don't condone the use of said technique. If you're fine with it -- that's okay. I don't know why you're going on about conformity -- I hate dithering and I would NEVER use it, but that's not because I'm going against a popular trend, more so just hate the style. However, I acknoledge it can look very good and it has its uses. Pillow shading is more or less useless and it looks like ass all the time.
