- Colour is the first differentiating factor I look for (and the reason I make most mistakes: Apple Music and Strava, Twitter and Skype)
- Cacophonies of colours do not work, newsstand, photos, are all recognised as colourful clutter
- Complicated graphics, or trying to fit in typography does not work. Very simple shapes stand out. And surprisingly, shadows of human postures (Amazon Kindle, the local taxi hail app), the brains is somehow trained to recognise these.
