Dear Cz or Cosmik,
Please, It's very simple. Go to the developper's team, just pull on the ear of the chief of coders and tell him to modify the code, so the transparency of the chat area will be opacified when the background is too bright.
Easy. Like the inventory trick.
-EDIT-
In the Foreman Dungeon in the Longuest Road Omni Base.
Have you played in the Lab Room ? Even without any light amplifier, have you ever try to read the chat ? LoL
