Screenshot 1: Branches 

Screenshot 2:Source

Actual Results

The "Branches" and "Tags" button text with #4C9AFF foreground color has an insufficient color contrast ratio of 2.8:1 with #FFFFFF background color.

This will make it difficult for people with low vision and color blindness to read standard text elements that have insufficient contrast.

Expected Results

On all pages, ensure that each foreground/background color combination presents a contrast ratio of at least 4.5:1 for standard text.

Workaround

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