Colorblind Accessibility

This mod changes some graphics of the game to make them easier to see and distinguish by colorblind players.

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

An updated Rebirth version of this mod is also available here![]


UPDATE November 28th 2021

Updated to be compatible with Repentance!

This fixes many reported issues, such as missing boss note icons. I also added some more new improvements, both for new Reptenance features and older ones!


For users with Tritanopia

Only a few changes are relevant for tritanopia. If you have tritanopia or tritanomaly, you can remove unecessary files like this:
  1. Open the mod folder. On Windows, this is usually in "C:\Program Files (x86)\Steam\steamapps\common\The Binding of Isaac Rebirth\mods".
  2. Delete or rename all included "resources" folders that are not labeled "TRITAN"
  3. Rename the remaining resources folders to remove the "TRITAN" label"
You may have to repeat this after every mod update.

Instructions for AB+ are in the readme.txt file.

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.

@LeTrying @Lünnsen The issues should be fixed now! Let me know if you encounter any other bugs.

When stuff breaks it's usually because of a game update, and I don't get notified for those, so I only notice them late. But do let me know if something's broken and I'll see it eventually!

@Magshine You can do this by opening the mod folder and deleting all the png and anm2 files except for the charge bar one. The charge bar one is "ui_chargebar.png" in resources/gfx/ui.

@meerkatboy2003 Unfortunately it's not possible for me to change visuals of different types of champions due to the way they're implemented. Maybe it's possible with the help of a mod programmer, but I'm not sure. I'm just an artist myself.

Gonna have a look at the bugs soonish.

is there a way to only have the charge and overcharge texture be changed, instead of everything this mod would normally affect?
Lünnsen Jul 10 @ 1:55pm 
I love this Mod BUT I found a weird bug.. I have tested it with every other mod I use (they are only asthetic mods like fancy trinkets or poofy hair) and the other mods are not the problem.

The Bug is simple; sometimes the podest on which the item is on isn't there and in the devil deals you can't see the prices. I only noticed it now because I always went for angel deals. It's only the devil deal that have this bug everything else works fine.

The update is finally out! The mod is now fully compatible with Repentance and all the issues should be fixed. There are new additions as well, including a Lucky Penny change suggested below. Be sure to check the change notes!

Let me know if I missed anything!

I'm working on an update to fix the glitches! I don't currently recommend using this mod with Repentance until I've posted the update.

Hi! I noticed the same issue as butters, the character progress note appears to be transparent when you beat Delirium.
(Your mod is still really neat!)
