Why Blumio

Built different.

Most blue light tools trade comfort for heavy color distortion. Blumio is built for long Mac sessions where you still care about natural-looking colors, fast control, and privacy.

GPU-Level Rendering

Modifies display color lookup tables directly on the GPU. No window overlays, no system slowdowns - just display-level blue light reduction.

No Special Permissions

No screen recording permission. No accessibility access. No orange dot in your menu bar. Blumio is private by design.

Not Just Orange

Blumio is designed to reduce harsher blue output while keeping colors more natural-looking than a heavy orange screen tint.

Smart App Exclusions

Automatically pause the filter when design apps, video players, or any app you choose comes into focus. Learn about app exclusions.

Global Keyboard Shortcut

Toggle the filter from anywhere with a customizable global hotkey. No need to open the app to switch it off.

7 Smart Modes

Task-based presets for Work, Coding, Reading, Movie, Gaming, Sleep, and Custom - one tap to switch. See recommended settings.

Common questions about screen comfort, filtering behavior, permissions, privacy, and daily use with Blumio. For a full search-friendly FAQ, visit the Blumio FAQ. If you don't find what you need, drop us an email.

How is Blumio different from Night Shift?
Night Shift is built into macOS and works well for basic evening warmth. Blumio adds menu bar controls, task-based modes, app exclusions, hotkeys, and display-only filtering for screenshots and recordings. Read the full comparison on the Blumio vs Night Shift page.
Does it work on all Macs and with multiple displays?
Blumio works on any Mac running macOS 13 Ventura or later. It applies the filter to all connected displays simultaneously using the GPU color lookup table API, so every screen in your setup gets the same filtering behavior.
Can I exclude specific apps?
Yes. Open the Exclusions panel from the menu bar popover, search for any app, and add it to your exclusion list. Whenever that app is in the foreground, Blumio automatically pauses the filter — and re-enables it when you switch away. Great for Figma, Final Cut, or any color-critical app.
Does it affect screen recording or video calls?
No. Because Blumio modifies display color output rather than placing an overlay window on top of your screen, screenshots and screen recordings keep the original colors. See the detailed explanation on the screenshots and recordings page.
How do I uninstall Blumio?
Quit Blumio from the menu bar (right-click the icon → Quit), then drag Blumio.app from your Applications folder to the Trash. All preferences are stored in macOS UserDefaults and will be removed when you delete the app. Your display returns to its normal color settings immediately on quit.
Can Blumio help with eye strain from looking at a screen all day?
Blumio is designed to make long screen sessions feel more comfortable by reducing part of the display's blue output. Many users prefer a milder setting during the day and a warmer setting in the evening. Comfort is personal, so the best approach is to start with Work or Reading mode and adjust from there.
Does Blumio run at login?
Blumio does not launch at login by default. To turn it on, open Blumio from the menu bar, click the controls section in the popover, and enable "Launch at Login."
