Hello! I absolutely love your game and have been enjoying it a lot.
I wanted to kindly suggest adding a colorblind mode in the accessibility settings.

In the efficiency view, I have a hard time distinguishing the percentage colors, and in many cases the 25%, 50%, 75%, and 100% values look very similar to me. A colorblind accessibility option would make this much easier to read and improve the experience significantly.

Thank you for your amazing work on the game and for considering accessibility improvements!
