Yes that maybe true about too bright colors, this is on todo list - i will be adding overlay effects, depending on the background so that screen look more natural in the current environment.
Something is slightly off about the mockups [1]. I'm not 100% sure what it is. Maybe the colors look too vibrant to be on an actual screen?
