Access the color settings through Fn + key combinations or keyboard software

The Leobog Hi75 has RGB backlighting that you can change using either hardware buttons on the keyboard itself or software on your computer. The quickest method is using Fn key combinations — hold Fn and press specific keys to cycle through colors or adjust brightness. If your keyboard came with software (usually called Leobog Driver or similar), you can also install that on Windows or Mac to access a full color menu with more precise control.

Which method works best depends on whether you want quick changes or detailed customization. Hardware buttons are faster for everyday adjustments. Software gives you access to profiles, timing, and effects that the keyboard alone cannot do.

Key Takeaways

  • Hold Fn and press the right arrow or left arrow key to cycle through preset colors on the Hi75.
  • Fn + Up arrow typically increases brightness; Fn + Down arrow decreases it.
  • If your Hi75 came with driver software, install it to unlock custom colors and lighting effects beyond the presets.
  • Different firmware versions may use slightly different key combinations, so check your manual or the Leobog website if standard combinations do not work.

Using Fn key combinations for quick color changes

The Leobog Hi75 responds to Fn + arrow keys for most lighting adjustments. Hold down the Fn key (usually in the bottom left of the keyboard) and then press the right arrow to move to the next color in the cycle. Press left arrow to go backward through colors. The keyboard will cycle through its built-in color palette — typically red, blue, green, purple, cyan, white, and off.

Brightness works the same way: Fn + Up arrow makes the backlight brighter, and Fn + Down arrow makes it dimmer. You can adjust brightness while any color is active. If you want the keyboard to stay on a single color, keep pressing right or left arrow until you reach the color you want, then stop adjusting.

Some Hi75 units also respond to Fn + Space to toggle the backlight entirely on and off. If these combinations do not work on your keyboard, your firmware may be different — check the manual that came in the box or visit the Leobog support page for your specific model number.

Installing and using Leobog driver software for custom colors

If your Hi75 came with a driver disc or a download link, the software lets you set any color you want rather than cycling through presets. Download the driver from the Leobog website (search "Leobog Hi75 driver" plus your operating system) or use the disc if one was included. Install it like any other program on Windows or Mac.

Once installed, open the Leobog software and connect your keyboard via USB. The program should detect the Hi75 automatically. Look for a color picker or palette section — this is where you can choose any RGB color by clicking on a color wheel or entering specific red, green, and blue values. Some versions also let you set different colors for different keys, create lighting effects that pulse or wave, or save multiple profiles.

After you set your colors in the software, look for a button labeled "Apply" or "Save to Device." This writes the settings into the keyboard's memory, so the colors stay even if you unplug it or restart your computer. If you later want to go back to the default presets, the software usually has a "Reset" option.

Troubleshooting when colors are not changing

If Fn + arrow keys do nothing, the keyboard may be in a mode that does not respond to those commands. Try unplugging the Hi75 from your computer, waiting 10 seconds, and plugging it back in. Then test the Fn combinations again. Some keyboards have a mode switch or a key that locks lighting controls — check the back or underside of the keyboard for a physical switch.

If you installed driver software but the colors still will not change, make sure the keyboard is plugged in via USB (not wireless, if your model supports both). The software can only control the keyboard when it is connected by cable. Restart the software and try again. If the problem persists, uninstall the driver, restart your computer, and reinstall it fresh.

Firmware updates can also change how the keyboard responds. Visit the Leobog website, find your Hi75 model number (usually printed on the back), and check whether a firmware update is available. If one is, download and install it — this may restore or change the key combinations your keyboard uses.

Understanding RGB color modes and effects

Most Leobog Hi75 keyboards offer a few built-in lighting modes beyond solid colors. Breathing makes the light fade in and out. Wave makes the color travel across the keyboard. Reactive lights up keys as you press them. On the hardware level, you cycle through these modes the same way you cycle colors — Fn + a specific key, often Fn + the spacebar or Fn + a number key.

If you have the driver software, you can usually customize these effects: slow down the wave speed, change how bright the reactive glow is, or set different effects for different key zones. The software interface will show you a preview of each effect as you adjust it, so you can see what it will look like before you apply it to the keyboard.

Saving and switching between lighting profiles

The Leobog driver software lets you create and save multiple lighting setups — one for work, one for gaming, one for low-light environments. Create a new profile in the software, set your colors and effects, and give it a name like "Office" or "Night Mode." Save it to the keyboard's memory using the Apply button.

Once you have multiple profiles saved, you can switch between them either through the software or, on some models, using a keyboard shortcut. Check your software's profile section to see whether it shows a hotkey for switching profiles. This is useful if you want different lighting for different times of day or different tasks without opening the software each time.

Frequently Asked Questions

Will changing the backlight color drain the battery faster?

If your Hi75 is wireless, brighter colors and active effects like breathing or wave do use more power than a solid dim color or backlight off. Turning the backlight off entirely saves the most battery. If your Hi75 is wired only, battery is not a concern.

Can I set different colors for different keys?

The hardware buttons (Fn + arrows) change the entire keyboard to one color at a time. The driver software on some Hi75 models does allow per-key color customization, but not all versions support this. Open the software and look for a "per-key" or "zone" option in the color menu.

What if I lost the driver software disc or cannot find it online?

Search the Leobog website directly for "Hi75 driver" and your operating system. If nothing appears, contact Leobog support with your keyboard's model number and serial number (usually on the back). They can send you a download link or advise you on which Fn combinations your specific version uses.

Do I need to reinstall the driver after a Windows or Mac update?

Sometimes. After a major operating system update, restart your computer and open the Leobog software. If it does not detect the keyboard, uninstall and reinstall the driver. This usually fixes compatibility issues.

Can I change the color of just the spacebar or arrow keys?

Only if your driver software supports per-key lighting. The Fn + arrow method changes the entire keyboard. Check your software's color menu — if it shows individual key icons you can click on, per-key customization is available on your model.
