Well, apart from what has already been said, I have a personal
experience of being on the receiving end of a Red brand. I bank with
HSBC, who in Australia have Red and Grey as their brand colours. Every
month I get a statement in Red print and every month I think I am in
debt or they are writing to warn me about something that is overdue.
Except this month. I have changed bank.
 
Regards

Jane

Subject: [WSG] Colour accessibility/ usability


Hi,

We've been asked to change our colour scheme on our websites to fit into
our corporate colour scheme.  We currently use blue, and the colour
we've been asked to change to is now red.  Our site will be using a
solid background, with white for the content area (along the lines of
news.com.au).  Our concern is that such a large amount of red may cause
accessibility/ usability issues (we are not only talking about the
background colour but also the navigation).  We may possibly have some
say into the shading of the red, but for the moment think of a nice
bright colour (#A80D35).

What we need more information about is how the colour red can affect
readability.  I have done research, and I know about the w3c colour
contrast algorithm.  I've also had a look at the psychology of the
different colours and that red is associated with anger and intensity.

What I am wanting to know, does anyone have any failure/ success stories
of using a large amount of red on a site without it adversely affecting
users.  We also wanted to know if there was a particular range that
might cause headaches in some users.  I would also be interested to know
of any research into what borders on acceptable luminosity.  For
example, I know in a couple of mockups that we have done, the red has
been very glary, and makes focusing on the content quite difficult.
Unfortunately, this being a personal opinion, we need the research to
back it up with.

Any help that you can give will be appreciated.

Regards,
Linda
