I read the article and it really hit the nail on the head, speaking as someone that is also r/g colorblind.

I recently bought an Amazon Basics charger for my rechargeable AA and AAA batteries. My old one had a bicolor LED for charging and charged. The new one shows red for charging and turns off for charged. I love not having to ask my wife when the batteries are charged anymore.

Now I just live in fear of colored graphs and charts where the legend has tiny small colored squares so you can distinguish which line is which.
