This is really disappointing. It's an integral part of the game, and I can't use it. Please, please provide a patch for this. I propose a quick color selector for the various existing color levels; this is because "color blindness" isn't necessarily the same between two color blind people. There are some who can see the shades of red and green used in the hack tool just fine, and there are others (like me) that can't. If you just change it arbitrarily then you may fix it for me and break it for someone else. For the record, I'm playing on the PS3. I also tried to search the forums to see if anyone already posted about this, but the search keeps giving me a database error.
When hacking, the needle moves across the dial. Pressing A on a green hacks, blue gives you a bonus (blue areas are not found on most hacking displays), white gives you an electric shock and red triggers the alarm. For those 6% of male gamers (only 0.1% of female gamers) who suffer from deuteranopia (a form of red-green colour blindness) this image shows what hacking looks like.
