1. Part of the inspiration for Colorblindly came from my disappointment with the existing alternatives. I wanted to make something that took advantage of the most recent tools for web development, and more importantly, worked on any page! But kudos to the other devs working on accessibility software, not enough love in this area.

2. Stylus sounds like something to look into, it should be pretty easy to adapt for use with it. Thanks for the tip!

Firefox version is next on my To Do List, hopefully in the next month! Thanks for your thoughts!

Hi all,

At my company we try to keep our website colorblind-friendly. I decided to spend my free time building an extension to help me do that and realized I could share this experience with the world.

What is surprising is how different everything looks for colorblind people - it's not just black and white like you might expect.

It works by placing a CSS filter over the page that distorts colors similarly to actual colorblindness-distortion.

This is my first Chrome Extension - I would love to hear your feedback!

Cheers, Andrew

This is neat but there is something quite wrong with the protanomaly/protanopia simulation. Look how it effects blue:

It adds a ton of red instead of removing it. Blues should be largly unaffected by protanomaly (though purples will turn to blue)

I think you're right, I'll look into this. Thank you!
