User blog comment:Bovell/Color blind assist option for Modern Warfare 3. Killstreak system reworked./@comment-69.251.92.75-20110708162112

That's nice they added it, but I don't think it's a new feature. In WaW and BO it wasn't labeled as a color-blind option, although there is an option for an 'alternate color scheme' which is similar to this.
