How Does Colour Blindness Affect Gamers?

For video gamers, it can mean some parts of games become vastly more difficult – such as when opposing teams are distinguished by the colours red and green, or if other crucial on-screen indicators feature similar shades.

Despite the large numbers of gamers affected, awareness among the development community is comparatively low. Only a handful of publishers make concerted efforts to cater to people with this genetic condition.

How Have Games Got Around This Situation?

Call of Duty Modern Warfare 3: This is the first Call of Duty that has implemented a colour blind assist and it features changing the mini-map icons, text and in game icons from red and green to another suitable colour. Though it only helps people with red and green colour blindness it can cause problems for others with another type of colour blindness.

Battlefield 3 & 4: In these two Battlefields they feature a colour blind assist for all types of colour blindness, and change the mini-map icons, in game icons and parts of the map to what the colour blind setting is on so that the user can carry on with ease, and therefore Battlefield is colour blindness friendly.

Borderlands 2: In Borderlands they implement all types of colour blind assist as they colour code most of the things in the game so to make it user friendly they added the colour blind assists so that the user can tell the difference between the items they are recieving, they put this is as from the original borderlands which didn’t implement this and gained a lot of complaints.

Dragon Age: When Dragon Age was first released it didn’t have a colour blind assist and this effected some users as they couldn’t tell the difference between some items in the game and couldn’t tell what some text was saying, so some time after the game was released they provided an update that added colour blind assist and were thanked deeply by its colour blind users. The colour blind assist added consisted of all types of colour blindness to help all.

Sim City: Sim City uses all types of colour blind assist and when they are turned on they change the game completely as the whole game uses a variety of colours so to make the game colour blindness friendly they made it so the game is clear to all with or without colour blindness.

What Elements of These Will I Implement In My Game?

I will implement the use of color blind assist so that anyone will be able to clearly understand my game and won’t have any problems with understanding what is in the game.
