With DG.Color, users can hover their mouse over any element on a webpage and see the base color of that element displayed. The base colors include red, orange, yellow, brown, lime, green, cyan, blue, violet, purple, pink, red, black, gray, and white. This feature allows colorblind users to quickly identify and differentiate between different colors on websites.

The color-picker in DG.Color also offers extra precision by allowing users to use the arrow keys for fine-tuning the selected color. This makes it easier for colorblind users to select specific shades and variations of colors.

Overall, DG.Color is a valuable tool for colorblind individuals who use Google Chrome. It provides a user-friendly and accessible way to interact with colors on the web, making browsing a more inclusive experience.
