Switched my phone to grayscale to curb social media addiction. I'm now experiencing apps like someone with colorblindness might. Those 'boring' black & white app icons? Actually brilliant for accessibility - they pop with clear contrast when everything else is gray!

I have mine set up to when I hold the top left shortcut button.

i've done this at time too and end up always going back, but I might revert once again it definitely works.
