PNG images can be up to 4096 × 4096 pixels.
Open a solid purple screen in fullscreen for mixed-channel testing, ambient light, pixel inspection, a saturated background, or a purple PNG.
Purple combines red and blue, so it can reveal channel imbalance and green-tinted pixel defects. Use the custom color control to move between violet, purple, and deeper magenta shades.
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.
