How to add an aurora effect to your iPhone keyboard
Aurora is a continuous backlight effect built on blending, not sweeping — two or three colours dissolving into each other the whole time the keyboard is open, which is a different trick from a rainbow wave’s single hue rotating across the keys, even though both run on the same kind of timer.
Somewhere you saw it: colour that does not so much sweep across the keys as breathe there, one shade dissolving into the next with no hard edge anywhere, closer to watching the sky shift than watching a light chase itself down a strip. It looks like something that has to live in Settings somewhere — Accessibility, maybe, or tucked in next to wallpaper. It does not, for the same reason a rainbow wave does not: Apple’s own keyboard has no lighting layer at all, so an aurora effect always means a different keyboard sitting on top of it, not a switch hidden inside the one already on the phone.
Why nothing like it exists in the built-in keyboard
The keyboard iOS hands every app is one piece of shared system code, and it draws exactly one thing underneath your fingers: flat keys, light or dark depending on the phone’s appearance setting, with no colour of its own and nothing moving behind them. Ambient colour that keeps shifting on its own needs an animation loop running the entire time the keyboard is open — a second piece of machinery Apple’s keyboard has never needed, because it was built to be neutral chrome, not a surface with its own decor.
What makes it read as an aurora rather than a wave
A rainbow wave rotates one hue steadily through the spectrum and sweeps it across the keys as a fairly distinct band — you can usually point to roughly where the colour currently is. Aurora works on a different principle: instead of one hue moving, it blends two or three colours into each other continuously, so the transition itself is the effect rather than a travelling edge. There is no moment where you could point at “the aurora” the way you can point at a wave’s leading edge — it behaves more like a slow-motion gradient than a light chasing itself across a strip, which is closer to what the real aurora borealis actually does: colour bleeding into colour rather than a shape moving through space.
One shared timer, the same as any continuous effect
Slow colour blending does not need sixty redraws a second to look smooth — a low frame rate already reads as fluid once the change between frames is gradual, and it costs the phone far less to sustain for as long as the keyboard stays open. Rather than animating each key on its own clock, a keyboard built this way typically drives every continuous effect — aurora included — off one shared timer that advances the whole animation together, which is both simpler to build and lighter to run than sixty independent redraws would be.
Why it stops the moment you close the keyboard
A continuous effect exists only while the keyboard extension itself is running on screen. Switch apps, dismiss the keyboard, or land in a secure field that falls back to Apple’s own keyboard, and iOS shuts the extension down along with whatever timer was driving the blend — there is no version of it quietly continuing in the background, because the code producing it stops existing the moment the extension does. Aurora is only ever visible for exactly as long as the keyboard is.
Adding one, start to finish
- Find a keyboard app that lists a continuous, colour-blending backlight effect and install it from the App Store like any other app.
- Open the app once — most take you straight to the right Settings screen from there.
- Settings → General → Keyboard → Keyboards → Add New Keyboard…, then tap the app’s name under “Third-Party Keyboards”.
- In any app, tap and hold the globe key 🌐 and choose the new keyboard from the list, or tap it repeatedly to cycle to it.
- Open the keyboard’s own settings — usually inside its app, sometimes a gear icon on the keyboard itself — and pick the aurora-style effect from the lighting list.
That is the entire setup. An effect that blends colour instead of sweeping it does not change any of those steps — it is still the same third-party keyboard, added the same way as any other.
Full Access has nothing to do with it
It is easy to assume a slower, more elaborate-looking effect needs a deeper permission than a simple one. It does not — Full Access governs a keyboard extension reaching outside its own sandbox, mainly the system clipboard and network access, and colour blending on screen touches neither of those, whether it is driven by a keypress or a timer. Aurora works exactly the same with Full Access left off.
Pairing it with a theme
Theme and lighting are usually two independent choices, so aurora ends up layered over whatever theme is already selected rather than replacing it. That matters more here than with a single-hue wave, because aurora is already doing the work of blending several colours together — laid over a theme that is also colourful or heavily patterned, the two blends can compete and the effect can lose its shape entirely. It tends to hold together best over a calmer, darker or more minimal theme, where nothing else is competing for the same attention.
Where Kibo fits
Aurora is one of Kibo’s 15 backlight effects, running in the continuous family alongside Rainbow Wave, Fire, Meteor and Starlight on the same shared 30fps timer, and it stops the instant the keyboard leaves the screen. It is picked separately from Kibo’s 56 themes, so it sits as comfortably over a Minimal or Dark theme as a Colorful one — and following the note above, that is usually where it reads best. Setup is the same as adding any third-party keyboard, and it works with Full Access left off, since that switch is only ever read by the Copy word, Copy line and Paste buttons on Kibo’s own toolbar. A starting set of effects is free to try, with the rest — Aurora included — unlocked through the one-time Kibo Pro purchase.
Frequently asked questions
Does iPhone have an aurora or northern-lights keyboard effect built in?
No. Apple’s own keyboard has no lighting layer at all, moving or reactive — it draws flat keys in whichever appearance mode the phone is set to and nothing else. An aurora effect always comes from a third-party keyboard added on top of it.
Is an aurora effect just a rainbow wave with a different name?
No — they work on different ideas. A rainbow wave rotates a single hue and sweeps it across the keys as a fairly distinct band. Aurora blends two or three colours into each other continuously, so the blending itself is the effect rather than a travelling edge of colour.
Does an aurora effect need Full Access turned on?
No. Full Access covers a keyboard extension reaching outside its own sandbox — the system clipboard and network requests, mainly. A backlight effect, aurora or otherwise, is drawn entirely on screen and needs neither.
Does a continuous effect like aurora use more battery than a reactive one?
It runs for as long as the keyboard stays open rather than only in short bursts after a keypress, so it does draw somewhat more than a purely reactive effect over the same stretch of typing. It still stops completely the moment the keyboard leaves the screen, so nothing keeps running in the background.
