PNG images can be up to 4096 × 4096 pixels.
Open a solid yellow screen in fullscreen for warm color checks, pixel inspection, bright ambient light, a visible background, or a yellow PNG.
Yellow combines the red and green channels, making it useful for spotting channel imbalance, uneven warmth, and pixels that appear blue or dark. It also provides a bright warm-toned light source.
Click the preview or Fullscreen to enter. Tap the fullscreen view or move the pointer to reveal the exit button, which hides after a few seconds. Esc also exits. If native fullscreen is unavailable, the view fills the page and browser controls may remain visible.
For a better display check, view several colors in a dim room and keep the browser zoom at its normal level. The tool displays solid browser colors; it does not calibrate the monitor or repair pixels.
