iOS: The almighty image filter has shown us just how powerful the slightest image tweak can be. You may not know it, but your iPhone is capable of doing the same colour-tweaking for its entire display.

Reddit user Pretentious_Fella points out that its easy to give an iPhone's colours more "pop". Apple has included this feature for users who may be colour blind, but anyone can head to the Settings app and access these options.
Simply navigate toward General > Accessibility > Display Accommodations, and then switch Colour Filters to the on position. From here, make sure to choose the Blue/Yellow filter, and enjoy your fresh (albeit artificial) coat of paint. That said, the tweak might not please everyone, and you may find you like more purplish-blues and neon greens (don't worry, the changes won't show up in screenshots).
iOS: Apple unveiled some killer new features in its WWDC 2018 keynote presentation earlier this month. In iOS 12 (which you can beta-test right now), users will be able to train Siri, stop sites from tracking them, and limit how much time they spend in apps. The worst part? These new features won't officially launch until spring.
Android smartphone owners have similar options, just navigate to Settings > Accessibility > Colour correction. Like iOS, you'll see three options for colour adjustments. Play around and pick what you like - if anything.
If you want to adjust your desktop or laptop's colours, you have even more options. On a Mac, the Display section of the System Preferences will have the options you need (under Colour). If you're on Windows, the Ease of Access section of Settings will let you choose your desired colours (under Colour filters).
