Color is an interesting subject. I'm color blind so there is always something that is the average person can see that I have difficulties seeing. For instance it was hard for me to see when the notification bell had the little dot one it. In this new version I can plainly see it.
The only thing I am having difficulties with so far is one of the member's signature. Part of it is a color that is hard to read.
The thing that is even more challenging for someone creating a board is not all coloring blindness is the same.
What I don't understand is I am red/green color blind and with all the green on the page I should have issues with the page. My guess is the contrast colors are the right ones for me.
