Keep bugs away while enjoying your device outdoors.
Reduce eye strain and improve reading comfort.
Yellow is psychologically stronger than any other color. It lifts the spirit and self-esteem; it is the color of confidence and optimism. Using a yellow background can subtly boost mental energy during creative blocks.
Photographers love \"Golden Hour\" (the hour after sunrise or before sunset). Use a full-screen yellow light to simulate this warm, flattering glow for selfies, product photography, or video calls, giving your skin a healthy, radiant look.
Cyan ink becomes invisible under pure yellow light. You can create \"secret messages\" written in light blue or cyan on a white paper, which will disappear when illuminated by this yellow screen, leaving only other colors visible.
Turn your tablet into a light box for tracing. The yellow background provides high contrast for dark lines while being less harsh on your eyes than a bright white background during long drawing sessions.
It doesn't \"repel\" them, but it doesn't attract them. Most flying insects are attracted to UV and blue light. Yellow light (wavelengths above 550nm) is less visible to them, so they are less likely to swarm your screen compared to a white or blue light.
Yes! A warm yellow background reduces the contrast between the screen and the surrounding environment, and filters out blue light. This makes it much more comfortable for reading e-books or documents for long periods.
Set your phone or tablet brightness to 100% and hold it just out of frame. It acts as a portable \"gel\" light, adding a warm, golden glow to your subject's face or creating a sunset effect in the background.
