> Key: AMBARI-5266

> Project: Ambari
> Issue Type: Improvement
> Components: client

> Reporter: Matt Foley

> Fix For: 1.5.1

> The following request was made by a colleague who did not wish to publicize
> his colorblindness:
> "I am green colorblind and the red/green service status dots look identical
> to me (especially on my Dell monitor, laptop is a little better though). I am
> sure that other people are affected by this as well. This may seem like a
> trivial request, but actually is quite inconvenient because to see service
> statuses, I now have to go down the list and click on each service
> individually."
> Evidently the particular shades of red and green currently used have very
> similar luminosity.
> Solutions are readily available in the Accessibility literature, including
> * changing palette to use red/green with significantly contrasting luminosity
> (This is a quick-fix, especially if the colors are palettized.)
> * adding text cue along with the color indicator
> * using a left/right or other non-color graphical cue along with the color
> * etc.
> A useful website for understanding the problem in the context of web pages is:
> * http://msdn.microsoft.com/en-us/library/bb263953(v=vs.85).aspx
> Please consider at least adapting the palette in the next release. Thanks.
