The latest update for StarCraft II: Heart of the Swarm goes a step in the right direction for those players who are color blind. Blizzard Entertainment announced plans to release update 2.0.10 for StarCraft II: Heart of the Swarm later this week that will add a new color blind mode and some new eSports features.
The new color blind mode alternates the colors that are used to designate players and shows the build grid when the "Display Build Grid" message is enabled. The minimap terrain is also darkened to show more visual contrast between units and terrain.
The update will also add new user interfaces tailored to shoutcasting and competitive play; various bug fixes; tweaks to certain aspects of Battle.net; and a whole lot more. You can learn more about the update on Battle.net.
