Turning my smartphone greyscale

I worry that I'm addicted to my phone. I feel naked without it and am constantly looking to it for stimulation. So, I'm starting an experiment where I turn my phone's screen to grayscale to make it less engaging. Ideally, this will encourage me to only look at my phone when I actively need to do something.

My hypothesis is that apps will be less interesting to me in black and white, and as a result, I'll feel less of an urge to grab my phone when I have a spare moment.

I'd like to change my balance of social connectedness, so that it's weighted more toward in-person interactions than lurking on Facebook. While it's tempting to feel like I know how my friends are doing because I see their pictures and their updates, there's no substitute for hanging out.
