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.

3. REBIRTH USERS: Copy the contents of the additional "REBIRTH (...)" folder into your game's resources folder. Do this AFTER adding the other files.

It's recommended to make a backup copy of your game's resources folder before installing the mod.


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.
