My upcoming game UpBot Goes Up relies a lot on colour to distinguish the different robots from each other. This can present a big problem to colour-blind gamers, something that is overlooked far too often by developers.
Here’s an example screenshot from UpBot, with the normal version first followed by simulations of three types of colour-blindness (created using this filter):
UpBot and DownBot (yellow and green) become especially difficult to tell apart.
To solve this UpBot features a colour-blindness option, that ends up looking like this:
The colours have been altered so that they are easier to tell apart. Each bot also has its own logo (the same shape as their eyes) to provide a definite difference. This logo is also used on the bots’ target zones.
An afternoon well spent I think – hopefully it’ll make a difference for a few people!
