Screenshot

Actual Results

The focus indicator on the "Platform", "Data Tools", "Global Trade", and so on expand buttons with foreground #4C9AFF focus indicator color have a contrast ratio of 2.8:1 with #FFFFFF background color.

This will make it difficult for people with low vision and color blindness to identify the focus indicator for the user interface controls that have insufficient contrast.

Expected Results

The contrast ratio between the foreground color of the focus indicator and its background color should be sufficient.

Ensure that the color contrast of focus indicator for all user interface controls is 3:1 with the foreground and background color.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
