Verification image at Registration
When I registered on the forums I had to ask my partner to read the letters on the image due to myself being colour-blind.
Perhaps it would be possible to amend the images so they are high-contrast and use only colours suitable for such users? I did search for an option to change the image but could only find an option to refresh, which didn't help.
Just a suggestion for accessibility.
I've fixed this so that the image colour does not alternate. Hopefully that means that colour blind users can simply refresh the image a couple of times until they see one that they can use.
Hope that helps, and thanks for the suggestion!
