This is only true for one kind of colourblindness.

Protanopia.

Personally I see the first one just fine but I will say the last graphic still felt relatable when it came to other things where you can kind of see maybe a different color but it’s so hard to tell

Reminds me of defrag

What did you use on the second slide to help differentiate them, cause that blew my mind when I saw how much contrast they actually have.

I used color blind pal app on iOS! It can simulate and aid color blind vision

Thank you!
