How to Tint Your iPhone Screen Red for Stargazing

If you want to make the most of your stargazing experience, one of the things you’ll need to prepare in advance is your iPhone.

Your eyes take 30-40 minutes to adjust to the dark and, once adjusted, if you happen to look at a bright, blue-toned light, like your iPhone, it immediately resets your night vision and you’ll have to wait all over again.

One way to avoid this is to set your iPhone screen to be tinted red. Red light doesn’t affect your night vision, so alongside having a red light torch (affiliate link), adjusting your screen settings is a great idea.

A super quick step-by-step guide to changing your settings

Open the ‘Settings’ app on your iPhone.

iPhone - Change iPhone settings for red tinted screen - 01 - Select 'Settings' app

(Optional) Scroll down to ‘Display/Brightness’ and tap it.

iPhone - Change iPhone settings for red tinted screen - 03 - Select 'Display & Brightness'

(Optional) Change your display to be in ‘light’ mode (if it’s not already). You don’t have to do this, but it does make it easier to read things once you’ve tinted it all red.

iPhone - Change iPhone settings for red tinted screen - 04 - Choose appearance - Dark
iPhone - Change iPhone settings for red tinted screen - 05 - Choose appearance - Light

(Optional) Go back out the main settings menu by tapping ‘< Settings’ in the top left of your screen.

Select ‘Accessibility’.

iPhone - Change iPhone settings for red tinted screen - 06 - Select 'Accessibilty'

Select ‘Display & Text Size’.

iPhone - Change iPhone settings for red tinted screen - 07 - Select 'Display & Text Size'

Toggle on ‘Increase Contrast’ (so it shows green and the circle is to the right).

This is to make some headings easier to read once your screen is red!

iPhone - Change iPhone settings for red tinted screen - 08 - Turn on 'Increase Contrast'

Toggle on ‘Differentiate Without Colour’ (so it shows green and the circle is to the right).

This is also to make some headings easier to read once your screen is red!

The description of the setting says ‘Replaces user interface items that rely solely on colour to convey information without alternatives’. Sounds good.

I’ve not noticed a lot of difference with this on, as yet, but it’s probably better to have the option than not be able to read something.

iPhone - Change iPhone settings for red tinted screen - 09 - Turn on 'Differentiate Without Colour'

Scroll down to ‘Colour Filters’ and tap to go into that sub-menu.

iPhone - Change iPhone settings for red tinted screen - 10 - Select 'Colour Filters'

Turn on ‘Colour Filters’ (so it shows green and the circle is to the right).

iPhone - Change iPhone settings for red tinted screen - 11 - Turn on 'Colour Filters'

Tap ‘Colour Tint’.

Set the ‘Intensity’ slider to max (all the way to the right).

Set the ‘Hue’ slider to red, which is all the way to the right.

iPhone - Change iPhone settings for red tinted screen - 12 - Choose 'Colour Tint' and move 'Intensity' and 'Hue' sliders all the way to the right

That’s it! You’re ready to go play out with the stars.

Also, consider setting your phone to silent or even put it on ‘Do Not Disturb’ mode, so you can relax and enjoy the night sky experience!

Getting your screen back to normal

When you’re ready to go back to normal you can just do the instructions in reverse, but if you’d like it broken down step-by-step, read on:

Open the ‘Settings’ app on your iPhone.

If it’s not already in ‘Colour Tint’, where you left it, from the main menu, scroll to ‘Accessibility’.

Scroll down to ‘Colour Filters’ and tap to go into that sub-menu.

Turn off ‘Colour Filters’ (so the switch shows grey and the circle is to the left).

Tap ‘< Back’ in the top left of the screen.

Toggle off ‘Increase Contrast’ (so the switch shows grey and the circle is to the left).

Toggle off ‘Differentiate Without Colour’ (so the switch shows grey and the circle is to the left).

Tap ‘< Accessibility’ at the top left of the screen.

Tap ‘< Settings’ at the top left of the screen.

Tap ‘Display & Brightness’.

Change the appearance back to ‘Dark’, if you want it that way.

Adding a shortcut to quickly switch between modes

If you’d like a quick way to be able to switch between the modes, we’ve got you covered!

Go to ‘Settings’ then ‘Accessibility’.

Scroll down to ‘Accessibility Shortcut’ and tap it.

iPhone - Change iPhone settings for red tinted screen - 13 - Select 'Accessibility Shortcut'

Tap ‘Colour Filters’ and ‘Increase Contrast’ so that they have a tick next to them.

iPhone - Change iPhone settings for red tinted screen - 14 - Tick 'Colour Filters' and 'Increase Contrast'

Now anytime you triple-click the side button (the big one on the right of the phone), a menu will pop up and you can select ‘Colour Filters’ and then ‘Increase Contrast’. Do it again when you want to switch them off.

Unfortunately, there isn’t currently a shortcut for Light/Dark mode or ‘Differentiate Without Colour’, so if you need those things you’ll have to go into the Settings app.

Go play! Have fun! We recommend the Grand Canyon, Death Valley and the dark skies of Pembrokeshire as excellent places to see the stars!
