e.g. 
I believe the two colors shown in the photo can be confusing for some people, especially those with color vision deficiency. it would be helpful if there is a clue other than colors, like different shapes, or if the brightness of the two colors makes a contrast, like bright red and thick green. i appreciate the simplicity of the current design and of course the change should not harm the visibility for people with normal vision, but i think there might be room for improvement. thank you for reading, as well as making and maintaining this amazing platform!
Never thought about it, but that's a good point. Maybe a green plus and a red minus would be better. That way the color scheme can remain, but be more helpful
edit: Something like this? 400 hours in photoshop btw
