I am working for a company, which web site uses red as its primary color, because this is the main corporate color (so, this could not be replaced).
The usual convention, of using red to highlight error messages, is being used, but messages are not actually being highlighted, because they seem to be other simple and conventional elements of the site.
I'm not a designer (I'm a backend developer), so I would like to have guidance from you UX/UI experts out there.
Any ideas?
