Please, LO, you need to make name tag colors adjustable. I'm color blind so this information is valuable and accurate for you.
The old G1 said color blind settings was a great idea..... in 2012..... of course they did nothing. Now guys are here to show how things are done.
Matt mentioned this briefly when he said changing the color of the crosshair would help color blind people.
But the most important part if you want to help the 8-10% (males. 1 of 200 in women) of people who are color blind is to make the actual nametag colors changable, not only into any color but to remove opacity, so they don't get affected by lighting conditions, background etc becuase that also messes it up for us color blind people, when it start blending with world colors etc.
I'm red/green color blind myself, so I'm telling you, this is what would really help. Some times, especially when there is no time to read what a name tag says, it is impossible to tell if it's a friendly or enemy name tag for us color blind people. It sucks having to tell people all the time that you're color blind when they get annoyed of you shooting at them.
The percentage of color blind people adds up to a fair amount of players as well.
