I want to do some scientificish reading on how grayscaling things helps. Anyone have any scienceish links?

Trigger warning. Links in this thread. ^probably

I spent a few mins on wiki trying to find something and found not much on it. A big area of weakness for me is googling something i want to research and then clicking some random interesting link and boom i'm gone. I'm hoping asking for help is way to get around it.

"Step 5: Turn On Grayscale

Our brains love bright and shiny things. By turning your screen to black and white you make your phone boring."

I'm particularly interested in the psychology of this.
