This article explains how to turn on high contrast mode and how to make your own high contrast theme.
Text with low contrast can be difficult to read for people with low vision. There are websites that have, for example, poor color combinations such as blue links on black backgrounds. They aren't easy to read even for people with unimpaired vision and can be virtually impossible for people with vision disabilities. Strongly contrasting colors can make it quicker and easier to read from your PC.
Turn contrast themes on or off
Select the Start button, and then select Settings > Accessibility > Contrast themes.
To turn on contrast themes, select the theme you want from the Contrast themes drop-down menu, and then select the Apply button. Windows may display a "Please wait" screen for a few seconds, after which the colors on the screen change.
To turn off contrast themes, select the None option from the Contrast themes drop-down menu, and then select the Apply button. Windows may again display a "Please wait" screen for a few seconds, after which the colors on the screen change back to default.
Tip: Press the left Alt key + left Shift key + Print screen (Print Scrn on some keyboards) to quickly turn high contrast mode on or off.
Make your own high contrast theme
If none of the default themes work perfectly for you, you can further customize the colors of various screen elements. For example, if you have some form of color blindness, you can swap out the affected colors.
After selecting a theme, select the Edit button under the Contrast themes drop-down menu. You can modify the color of the following screen elements:
Background: the background of nearly all text you see in Windows or on a web page, for example.
Text: nearly all text you see in Windows or on a web page, for example.
Hyperlinks: all hyperlinks you see in Windows or on a web page, for example.
Inactive Text: text that would normally be grayed out, for example, when you cannot select a specific option or button.
Selected Text: any selected menu item or option. For example, the alignment of the currently selected paragraph in Word is indicated with this color on the tool ribbon.
Button Text: text on any buttons that contain text.
Select a new color by clicking on the color picker palette, adjust the selected color's brightness using the slider under the palette, and select Done.
To save any color changes you have made to the theme, select Save as and type a name for your custom theme. Then select Save and apply.
