I wanted to hop on to speak to this issue a bit, as it’s certainly something our team cares a good deal about. As some of you may know, we’ve been preparing a big update to StarCraft II (patch 1.5) that will introduce a number of welcomed features to the client -- one of which is the ability for us to stream content updates to the game. This will allow for quicker access to a play session (removing the need to wait for patches to fully complete) and remove the need to repair your client files, as they’ll be constantly kept up to date automatically.

One of the unfortunate side effects of streaming is that mods that alter the StarCraft II archive files will no longer function, including color-clarity mods, custom Battle.net background mods, and more. Although these types of archive modifications go against our EULA and can also be used to spread malicious viruses or Trojans, we do understand the merit of many of these features. With the color-clarity issue specifically we actually have a few people on the team who are affected by color-blindness.

The development team is looking into options now to support color clarity and customized backgrounds as well as some of the other mod features. We believe that in the long run, it's best for us to provide an option like stronger team colors within the game, as opposed to an externally modded solution that we can't explicitly support.

We’ll keep the community updated on our progress and appreciate your continued feedback.
