This mod changes some graphics of the game to make them easier to see and distinguish by colorblind players.
It's compatible with Rebirth, Afterbirth and Afterbirth+.

This is a continuation and overhaul of the original Colorblind Accessibility mod by CyborgDragon.


UPDATE October 15th

Added a few improvements, and changed the charge bar back to be filled green, now with colored outline when overcharged.

There is now an extra Tritanopia-only folder since there are only very few changes needed for it. Install this if you don't need the other files.

Hope this helps! I've tried to account for different kinds of color blindnesses, but as I'm not colorblind myself, I can only rely on simulations and feedback. If I missed any important things, let me know!

Special thanks to CyborgDragon for starting this project in the first place and letting me continue it.
