Checking for colour blind accessibility

[jacquidow]

I am looking for a tool that I can run an image/website through and it will tell me if it is accessible for colour blind users. I have used VisCheck in the past but this does not appear to be working any more.

Thanks in advance

Maybe the Chrome plugin Alessia found will be useful for you too?

How can I create a set of colors with the same readability/contrast?

Thank you very much Bleke…! Unfortunately, on this computer, I don’t have Photoshop so I downloaded Gimp when I viewed your answer - and I can’t found the command. You’re very kind, It’s really interesting! I found a similiar tool for webpage --> https://chrome.google.com/webstore/detail/nocoffee/jjeeggmbnhckmgdhmgdckeigabjfbddl
