# 调整对比度

You can adjust the contrast of windows and buttons so that they're easier to see. This is not the same as changing the brightness of the whole screen; only parts of the user interface will change.

Open the Activities overview and start typing Universal Access.

Click on Universal Access to open the panel.

Switch High Contrast to ON in the Seeing section.

# Quickly turn high contrast on and off

You can turn high contrast on and off by clicking the accessibility icon on the top bar and selecting High Contrast.
