How to Change the Background (Backlight) of Your Keyboard

Whether you're typing in a dim office, gaming late at night, or just want your setup to look a certain way, keyboard background lighting — commonly called backlighting or RGB lighting — is one of the most visible and customizable features on modern keyboards. But "changing the background of your keyboard" can mean very different things depending on what keyboard you have and what platform you're on. Here's what's actually happening under the hood, and what controls what.

What "Keyboard Background" Actually Means

When most people refer to the background of their keyboard, they mean the backlight — the glow that illuminates the keys from beneath. This can range from a single static color to complex animated lighting patterns across millions of color combinations.

There are a few distinct types:

• Single-color backlit keyboards — Emit one fixed color (often white or red). You can typically only adjust brightness, not hue.
• RGB keyboards — Use red, green, and blue LEDs per key, allowing full-spectrum color mixing and per-key customization.
• Zone-lit keyboards — Divide the keyboard into sections (left, center, right), each controllable as a group.
• Non-backlit keyboards — No lighting hardware at all. No software will add backlighting if the physical LEDs aren't there.

Understanding which category your keyboard falls into is the first step, because the methods available to you are entirely determined by the hardware.

How to Change Keyboard Backlight on Windows

On Windows laptops, keyboard backlight controls are usually handled one of three ways:

1. Keyboard shortcut — Many laptops use a Fn key combination (e.g., Fn + F5, Fn + Spacebar, or Fn + arrow keys) to cycle through brightness levels or colors. The exact key varies by manufacturer.
2. System Settings — Some manufacturers integrate lighting controls directly into Windows Settings or a dedicated control panel (common on Dell, HP, and Lenovo devices).
3. Proprietary software — Brands like ASUS (Armoury Crate), Acer (Predator Sense), and MSI (Dragon Center/MSI Center) bundle software that gives more granular control over color and effects.

For desktop mechanical keyboards on Windows, you'll typically use either:

• Onboard controls — Key combinations programmed into the keyboard's firmware, accessible without any software.
• Manufacturer software — Apps like Razer Synapse, Corsair iCUE, SteelSeries GG, or Logitech G HUB, which unlock per-key RGB programming, animated effects, and profile saving.

How to Change Keyboard Backlight on Mac

macOS handles keyboard lighting differently. On Apple MacBooks, backlight brightness is controlled via System Settings → Keyboard, where you can toggle automatic brightness adjustment and manually set the level using the brightness keys (F5/F6 on older models, or through Control Center on newer ones).

Apple's keyboards do not support RGB color changes — they're white backlight only, with brightness as the only variable. Third-party apps exist that claim additional control, but hardware limitations apply.

For third-party RGB keyboards connected to a Mac, you'll need the keyboard manufacturer's software — though not all manufacturers offer macOS-compatible apps. Compatibility is worth checking before assuming full RGB control is available on macOS.

How to Change Keyboard Backlight on Smartphones and Tablets 📱

Some Android phones and tablets with physical keyboards (or keyboard accessories) support backlight changes through:

• Bluetooth keyboard companion apps
• Device settings under Language & Input
• The keyboard accessory's own hardware buttons

On-screen keyboard apps (like Gboard or SwiftKey) let you change the keyboard theme — which is a visual skin, not a hardware backlight. This includes background colors, key colors, and fonts, all managed within the app's settings menu.

RGB Keyboards: What Software Actually Controls

For enthusiast-grade RGB keyboards, the depth of control varies significantly:

OpenRGB is a popular open-source alternative that works across multiple brands, useful if you want unified control without running several manufacturer apps simultaneously.

The Variables That Determine What's Possible for You 🎮

Several factors shape what lighting options are actually available to you:

• Hardware generation — Older keyboards, even from RGB-capable brands, may have fewer LEDs or less capable firmware.
• Operating system — Some manufacturer software is Windows-only, leaving macOS and Linux users with onboard controls or third-party workarounds.
• Keyboard connectivity — Wireless keyboards sometimes have reduced lighting options to preserve battery life.
• Firmware version — Manufacturers push firmware updates that add or modify lighting features. An outdated firmware can mean missing effects or buggy color rendering.
• Budget tier — Entry-level keyboards in a product line often have zone lighting or single-color options, while premium models support full per-key RGB.

When the Physical Hardware Sets the Hard Limit

No software — no matter how sophisticated — can add a color to a single-color LED, add per-key control to a zone-lit keyboard, or create a backlight where no LEDs exist. Software unlocks and refines what the hardware supports; it doesn't override it.

This distinction matters when troubleshooting. If you've installed the right software and still can't get full RGB, the limitation is almost certainly in the keyboard's LED hardware itself — not the app or the driver.

What's achievable for your keyboard specifically comes down to the intersection of its physical LED setup, the firmware it's running, the software available for your OS, and how much control you want day-to-day versus just a set-it-and-forget-it glow. Those variables are unique to your exact combination of hardware and platform.
