With much respect and detail our PernixData engineers are interested in every facet of the customer experience. Something that may seem small to others can be a big deal to some. It’s with this that PernixData thinks about every feature in a holistic manner that all can appreciate. One such feature that fits this model is providing visual accessibility to those with color blindness. With 1 in 12 men and 1 in 200 women having some form of color blindness, it becomes important that the FVP UI is readable and understandable no matter the impediment.
It was in FVP 2.0 that we made modifications to the colors in our UI to deal with the most common forms of color blindness: Deuteranopia (~5% of males), Protanopia (~2.5% of males), and Tritanopia (~.3% of males and females). For example, the “Network Acceleration” line graph was made to be lime green. In addition all colors were tested with “Color Oracle” and application that simulates different forms of color blindness.
In addition, we made it easy to recognize each line on a chart uniquely identifiable. This was accomplished by providing the ability to toggle lines on/off. For example, if you aren't sure which line is referring to the datastore, just toggle the others off or toggle the datastore selection off/on, and this will clearly show the datastore line.
When designing the FVP interface it was also recognized that color is used as a secondary source of information that provides further insight and impactful information to the primary source. For example, in the host/flash device visualization, the color of the tiles (red, green, yellow) indicates the state of the relevant object. If there is a problem however, alarms/warnings also show an exclamation point on the tile in addition to the coloring of the tiles.
