Today we are going to write about the first accessibility feature that we have implemented in Your Computer Might Be At Risk: color blind mode.

There are various types of color blindness with different alteration grades of color perception. Analyzing our gameplay and its handicaps, we have developed modes for Protanopia, Deuteranopia and Tritanopia.

In general, when the players activate one of these modes we search for the problematic colors in the game puzzles and change them to select colors that are easily readable for the selected color blindness mode. At some points where there are many colors at the same time we also needed to add a symbol to differentiate them. There are a lot of resources on the internet to check the problematic color range, but we can recommend this video as a good summary:

For example, we have many puzzles that use the red and green colors as opposites. This duo is problematic for color blindness, so what we do is maintain the red color and change the green one for another that is valid.

However, some puzzles in the final chapters of the game (wich we can’t talk about, spoilers and stuff 🤭), were too complicated even with the new colors, so when a player activates the color blind mode these special puzzles slightly change its mechanics and solutions to achieve a fair experience.

To conclude, if you are developing this feature in Unity, we can recommend this package that changes the screen rendering to show each type of color blindness with just a click:
