Colour filters come to iOS 10

colour tint iOS 10Even though you could have colour filters on the Android and your desktop it has only been possible on the iPhone and iPad since the introduction of iOS 10.  These filters can be useful for dulling the screen, offering different choices of colour overlay for those with colour deficiencies or visual stress.  Go to Settings > General > Accessibility > Display Accommodations > Colour Filters. Turn them on and there is a choice of filters with the names of different colour deficencies such as Protanopia Red/Green filter.  Go to the bottom of the list and there you will find the colour tint that allows you to choose a hue and the intensity to suit your preference.

These filters have also been exciting star gazers as they provide a form of night vision according to Dave Mosher from Business Insider UK.

I’ve found that Screen Adjuster for Android works well at tinting and adjusting brightness of the screen. Screen Adjuster allows you to change contrast, brightness and colour of the screen really quickly and easily.
However, working with the app can be very frustrating when you want to move the sliders near the edge of the touch screen.  The swipe gesture may not always respond.   Otherwise the app is free and easy to use and can even dim the screen below the system settings.

Screen Adjuster runs on Android 2.2+ and is on Google Play – there is a version that costs 0.73p that comes without the advertisements.
