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.
Choose a preset or custom color before opening the preview in fullscreen. Press Esc to leave fullscreen, then adjust the color and open it again.
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.
