It’s not a big deal to colorblindguys, but we can not easily read certain color combinations. The worst is red on black. I’ve seen the Biden sign a couple of times (at a podium and lawn signs) and read it as Bid n. I was able to figure it out especially when he was speaking at the podium with the sign just below him. So I’ve added given the red “E” a stoke to allow us to read it immediately-and I think that’s the point. I’m aware it’s not artistically great but I can read it. Is it supposed to resemble a flag?
I added another example below.
Had no idea that there was a heading for the items on the right.
