Curious to see for myself (no pun intended) just how much impact being colour blind makes to the new hacking mechanic, I ran the above image (sorry for the low quality, it’s a photo of the 360 version) through a colour contrast analyser application I used when re-designing this very site (you can download it here).
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) the image below shows what hacking looks like.
If you’re in the 1% of males (0.01% of females) with protanopia (another form of red-green colour blindness) this image shows you what you’re up against.
Finally, if you’re in the 0.01% of gamers (using averages this estimates to a few hundred BioShock 2 players) with tritanopia (blue-yellow colour blindness) this is your hacking.
Hopefully 2K take note and patch in some colour-changing options.
