Status of the Color Usage
The authors of the Color Usage Site are no longer with NASA. The website is being maintained in its final form as a public service:
Larry Arend has retired from NASA
Alex Logan has returned to the Silicon Valley private sector

The Color Usage
Site was developed by Larry Arend, Alex Logan, and Galina Havin.

Comments and suggestions about the Color Usage Site should be directed to
The Color Usage Website is intended to help with development of safe,
usable designs for complicated information displays, especially aerospace
The website is directed
mainly to people who are designing graphic content for aerospace (and
similar) electronic displays. These are expected to be mostly software
engineers and graphic arts experts rather than color scientists or
human factors engineers.
general idea is to provide concrete and practical advice at the top level
of the website. Further information is available via links, some of it
regarding finer points of design and some explaining where the top-level
advice comes from (more technical, applied color science).
With few exceptions
we have included only things that can be directly demonstrated on the
site. The rationale for this is that if it doesn’t occur on your
display of the website it’s probably not a first-order issue in
other applications (important exception: a few issues might be more/less
important in longterm, familiar use).
