Make the annotation tool in Watson Discovery colorblind safe

During a recent Client Enablement Workshop, we presented an overview of Watson Discovery and followed it with a hands-on session. This allowed participants to explore the product through guided exercises.

However, we encountered an important accessibility issue. One of the participants, who is colorblind, shared that he struggled to differentiate between the annotation colors used in the Smart Document Understanding labeling tool (a fair request, the color selection is unfortunate, and and even myself I had sometimes troubles to make distingtion between subtitle or title fields...)

We discuss with the client, that a key limitation is that when hovering over the colored fields, no additional information is displayed - such as the name of the selected field - making it difficult to confirm what has been annotated. Additionally, while it's possible to create new fields and assign them colors, there is currently no way to modify the color of these fields after creation.

For users with impaired vision, this creates a significant barrier. I have promised the client, I will make a request, listing the following enhancements to improve accessibility:

1.  Display the name of the selection when hovering over annotated elements
2.  Allow users to modify the color of existing field labels (both the original and the newly created).

These small changes could make a meaningful impact in improving the usability and accessibility of the tool for all users.
