I too find a bright red (usually useless) notification badge (for ex) very distracting, this helps me focus on the content a ton (along with setting #header and #footer to {display: none} on 99% of sites)
Notification badges (the red number) seem less urgent when viewing the Home Screen. Content in apps (octal, Apollo) seems less engaging. I spend less time on my phone when it’s all shades of grey.
Now triple clicking the side button will toggle greyscale. Disable it when you want to look at photos, enable greyscale for all other applications.
