In the top left corner of the website you will see the High Contrast toggle.
High Contrast Toggle
The high contrast toggle is a feature that site admins can turn on/off on a per site basis. It shows up at the very top of the site, and when turned on, converts the template colors to black and white. This provides visually impaired users with an enhanced experience, and helps to safeguard against color contrast violations. All MyWay Ultra templates include this feature, and it can be added to any custom template.
