I cannnot read much of the chat contents as the colour contrast between the names, text, and background, are too low.

Consider this example, from https://support-portal.plarium.com/en/throne-web/faq/orders/pacts

The bottom message's name and message I can only barely make out. The prior two lines of names and text, not at all.

Could higher contrast colours please be chosen, or better yet, make it user configurable.
