If CandyCrush got you hooked and you haven't been able to break the cycle since, then the news that your mobile phone can actually be as addictive as gambling machines might make a lot of sense.
There's a lot of science about colour and what affect it has on the body: white makes us feel clean and neutral, red elicits feelings of love and romance, orange is for happiness and excitement, yellow brings out happiness and optimism and green helps us to feel cool and harmonious. Couple all the good feelings colours give us with the great big smack of dopamine - a hormone that makes us feel good when we're rewarded - that we get when we check our phones and find a slew of positive Facebook notifications or alerts that CandyCrush has awarded us with something new, it's no wonder no one can seem to find the time to be without their phone.
Tristan Harris is a former design ethicist from Google, who seems to think that deterring that niggling addiction to the colours, lights, sounds and validation our mobile smart phones and all the apps on them give us might just be a colour change away.
Harris suggests that changing your phone screen settings from colourful to greyscale (which you can do very easily!) is a way to really suck the anticipatory enjoyment out of staring at all those blank apps on your phone, waiting for something to happen. He likens our behaviour with our phones and our idle staring at them to the addiction of pokies machines in casinos, which are equally as colourful, fun and loud to draw people in for hours. It's convincing, right?

This varies from phone-to-phone, so check with your manufacturer.
See if it makes a difference to how much time you feel compelled to fiddle with your mobile phone for no apparent reason!
