In my work with my own app I started to think, what is the best color for an app icon? Started to search for information and it´s really fascinating stuff, colors..it´s psycological cause it affects our emotions, our actions and how we respond to certain things.
How do you want your app to be perceived, what is your target audience. Your app icon colours should reflect that, for example the colour blue which is the most popular color especially for men often associated with trust. Have you seen any blue app icon colours out there? =) So for business for example I guess blue is the one. Here are some meanings of different colors:
Red symbolizes: action, confidence, courage, vitality
Pink symbolizes: love, beauty
Brown symbolizes: earth, order, convention
Orange symbolizes: vitality with endurance
Gold symbolizes: Wealth, prosperity, wisdom
Yellow symbolizes: wisdom, joy, happiness, intellectual energy
Green symbolizes: life, nature, fertility, well-being
Blue symbolizes: youth, spirituality, truth, peace
Purple symbolizes: Royalty, magic, mystery
Indigo symbolizes: intuition, meditation, deep contemplation
So depending on what type of app you do maybe you should give the app icon color some extra thoughts. Read an article just now from 2011 saying that in the Top 100 app icons, 40 of them is blue, 36 is green (quite surprising for me actually) and after that red.
For my app, it feels quite boring to say but it will be blue 😉
Thats´s all for now, thanks for reading. Keep in touch and feel free to comment.
