I'm working on a design at the moment that has a "tab panel" in the page.
In the first iteration the visual designers used reverse colour on the main
type to distinguish between the selected tab and the unselected tab. This
type of colour reversal is a classic graphic design trick to decrease the
visual noise on a page.
My problem however is I think this kind of that it can introduce interaction
It is well known that we selectively attend on the basis of colour - in
other words if you are tuned into black text you will tend to not see any
white text. This is exactly the reason why the classic graphic design trick
For the user this results in a kind of "tab blindness" - an effect I've seen
in a number of testing sessions.
Has anyone come across this observation or any design guidelines that advise
against colour reversals in navigation devices?
