Frequently Asked Questions

WhiteScreen.wiki is a free, ad-free online tool that transforms your browser into a full-screen color environment. Choose from nine calming colors — white, blue, green, black, red, yellow, pink, cream, or gray — to create a distraction-free workspace for focus, meditation, or relaxation.

Think of it as a digital canvas for your mind. Unlike cluttered productivity apps, WhiteScreen.wiki embraces minimalism. There are no notifications, no timers counting down, no metrics to track — just pure, calming color.

The tool is built on color psychology research showing that different colors can influence cognitive performance, mood states, and visual comfort. No apps to install, no accounts to create. Just open the site, pick a color, and enter fullscreen mode.

Yes, 100% free. There are no ads, no subscriptions, no premium tiers, and no hidden costs. WhiteScreen.wiki was built as a public resource for anyone who needs a calm digital space.

We believe that access to simple focus tools shouldn't be behind a paywall. In a world where most digital experiences are designed to capture attention and extract data, we wanted to create something different — a tool that respects both your focus and your privacy.

This site will remain free forever. We don't sell data, we don't show ads, and we never will.

Using WhiteScreen.wiki is simple:

1. Visit the Colors page to see all available color options
2. Click any color card to instantly launch fullscreen mode
3. Focus, meditate, or relax with your chosen color filling the screen
4. Press ESC or click the X to exit fullscreen when you're done

That's it! The site automatically remembers your last color choice, so returning is even faster. You can also bookmark specific colors using URL hashes like colors.html#blue.

WhiteScreen.wiki automatically remembers your last used color using your browser's localStorage. When you return to the site, your preference will be highlighted and ready to use.

You can also create direct bookmarks for instant access:

• whitescreen.wiki/colors.html#white — Pure white screen
• whitescreen.wiki/colors.html#blue — Calming blue screen
• whitescreen.wiki/colors.html#black — Dark meditation screen

This data stays entirely on your device — it's never sent to any server.

Research suggests different colors optimize different types of cognitive work:

• Blue screens are ideal for analytical tasks, reading, and detail-oriented work. A University of British Columbia study found blue enhances creative performance and careful attention to detail.
• Green screens excel for long study sessions because green reduces eye strain and promotes sustained concentration without fatigue.
• White screens provide a neutral canvas for writing, minimizing distraction and helping you focus purely on your thoughts.
• Cream screens offer the benefits of white with reduced glare, making them excellent for extended reading or writing sessions.

That said, individual responses vary. We recommend experimenting to discover what works best for your brain and your tasks. Learn more about color psychology research.

Yes, color psychology is supported by peer-reviewed research. Here's what science tells us:

• Neurological basis: Your eyes contain specialized cells called intrinsically photosensitive retinal ganglion cells (ipRGCs) that respond to light wavelengths and influence brain regions controlling alertness, mood, and cognitive function.
• Blue light effects: Research published in Nature shows blue wavelengths (around 480nm) are particularly effective at activating alertness pathways in the brain.
• Red vs. blue study: A 2009 study at the University of British Columbia found that red enhanced performance on detail-oriented tasks while blue boosted creative thinking.
• Green and restoration: Environmental psychology research consistently shows green environments reduce mental fatigue and support attention restoration.

While individual responses vary based on cultural background, personal associations, and even genetics, the overall body of evidence supports that colors meaningfully influence cognitive performance and emotional states.

Several colors have calming properties that may help reduce anxiety:

• Blue — Associated with lowered heart rate and blood pressure. Blue environments feel expansive and peaceful, making them ideal for stress relief.
• Green — Evokes nature and has been shown to reduce cortisol (stress hormone) levels. Particularly effective because our eyes are most sensitive to green wavelengths.
• Cream/Soft White — Provides warmth without stimulation. The neutral tone creates a sense of safety and comfort.
• Gray — Offers visual "quiet" that can calm an overstimulated mind. Its neutrality provides a blank slate for mental reset.

For acute anxiety, try combining a calming color screen with slow, deep breathing. The visual simplicity helps anchor your attention away from racing thoughts.

If you need an energy boost or heightened alertness, consider these colors:

• Red — The most stimulating color. Red increases heart rate, adrenaline, and metabolism. Use for short bursts when you need maximum alertness, but avoid for extended periods as it can increase anxiety.
• Yellow — Activates the nervous system and stimulates mental activity. Yellow promotes optimism and can help overcome mental blocks. Best for creative brainstorming.
• White — High-contrast white screens promote alertness through brightness. Effective for morning routines when you need to wake up mentally.

Pro tip: Use stimulating colors strategically in short sessions (15-30 minutes), then switch to calming colors for sustained focus.

A white screen at appropriate brightness levels is not harmful to your eyes. The key factors for eye comfort are:

• Brightness matching: Adjust your screen brightness to match your ambient lighting. A screen that's much brighter than your surroundings causes strain.
• The 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds. This relaxes the focusing muscles in your eyes.
• Blink rate: We blink less when looking at screens, causing dry eyes. Consciously blink more often or use lubricating eye drops.
• Screen distance: Position your screen at arm's length (about 20-26 inches) from your eyes.

If white screens feel too intense, try our cream or gray screens which provide similar benefits with reduced brightness. Green screens are particularly gentle on the eyes for extended use.

Green is generally considered the easiest color on the eyes. Here's why:

• Human eyes have the highest sensitivity to green wavelengths (around 555nm), meaning we perceive green with less effort.
• Green doesn't require your eye muscles to adjust as much as other colors.
• Looking at green has been associated with reduced eye strain and faster visual recovery.

Other eye-friendly options include:

• Cream — Soft warmth without harsh brightness
• Gray — Neutral and non-stimulating
• Black — Minimal light emission (best for dark environments)

For long sessions, avoid pure white at high brightness and limit red exposure, which requires more visual processing.

The best choice depends on your environment and personal preference:

Use light/white screens when:

• Working in well-lit environments
• Needing to stay alert and focused
• Reading or doing detail-oriented work
• During daytime hours

Use dark/black screens when:

• Working in dim environments
• Using screens at night (reduces blue light exposure)
• Meditating or winding down
• Experiencing eye fatigue from bright screens

Research shows that high contrast (either white-on-black or black-on-white) is easier to read than low-contrast combinations. For pure focus without text, match your screen brightness to your room lighting for optimal comfort.

Absolutely. Many users find color screens ideal for meditation practice:

• Black screen — Eliminates visual stimulation completely. Perfect for closed-eye meditation or trataka (gazing meditation) in dark rooms.
• White screen — Creates a sense of openness and spaciousness. Good for open-awareness practices.
• Blue screen — Promotes calm and expansiveness. Associated with sky and water imagery common in guided meditation.
• Cream/Gray — Gentle, neutral options that neither stimulate nor strain.

How to meditate with WhiteScreen.wiki:

1. Choose your color and enter fullscreen mode
2. Set a timer on your phone (start with 5-10 minutes)
3. Sit comfortably with good posture
4. Softly gaze at the screen or close your eyes
5. Focus on your breath, returning attention gently when it wanders

WhiteScreen.wiki is a valuable tool for photography and video production:

• Softbox alternative: Use a white screen on your monitor or tablet as a soft light source for portraits or product photography.
• Color gels replacement: Create colored lighting effects without physical gels. Red, blue, pink, and other colors can add dramatic lighting to your shots.
• Green screen testing: While not ideal for full chromakey, the green screen can help test green screen setups and lighting.
• Exposure reference: Use white and black screens to calibrate camera exposure and check for sensor dust.
• Background lighting: Place a device behind translucent materials for even, colored backlighting.

Pro tip: For the best light source quality, use the highest brightness setting and position the screen at a 45-degree angle to your subject.

Yes! Fullscreen color displays are useful for testing monitors and screens:

• Dead pixel detection: Use white, black, red, green, and blue fullscreen modes to identify stuck or dead pixels. Dead pixels will appear as tiny dots that don't match the screen color.
• Backlight bleed check: Display a black screen in a dark room to reveal any light bleeding around the edges of your monitor.
• Color uniformity: Check if colors display evenly across the entire screen using different solid colors.
• Burn-in check: After displaying solid colors, switch to gray to reveal any image retention or burn-in.

This is particularly useful when buying a used monitor or checking a new display for defects.

If you need quick lighting for video calls, WhiteScreen.wiki can help:

• White screen: Open on a second monitor or tablet positioned to face you. This provides soft, even front lighting that reduces shadows.
• Cream screen: Slightly warmer tone that's more flattering for skin tones than pure white.
• Avoid: Red and green screens can create unflattering color casts on your face.

Setup tip: Position the light source (screen) at eye level or slightly above, facing you. Place it behind your camera for the most natural-looking illumination.

Once you've loaded the page, the color screens will continue working even if you lose internet connection. The fullscreen color display is generated entirely by your browser using CSS — no server connection required.
