On the color, I definitely prefer the light version; much easier to
read. Any of the colors actually work, I think.<br>
<br>
On the monotone, I actually LIKE the object storage nodes the best,
though that's not saying much; I don't like the monotone much at
all, actually, particularly compared with the color. At small font
sizes, I don't tink there's enough contrast on the baqckground
colors. The content colors are good, though. That's why the Object
Storage nodes work, I think. (Still prefer the color/light version,
though.)<br>

Nice job finding this.<br>

vary by document and sometimes look rather hideous. For example, I
used the red-green-blue theme in the installation guide to improve
contrast among the networks, but it lacks the civility you would
find in other professional documentation. Similar to networking,
colors are hard. For example, themes that implement many shades of
one or two colors look professional but limit the ability to
contrast important items. On the other hand, themes that implement
many diverse colors offer many ways to contrast important items,
but look harsh. I haven't found a theme that provides a decent
balance until Robb Romans (a coworker at Rackspace) pointed out
the Solarized theme [1] today. Although somewhat optimized for
text, this theme provides several decent dark/light combinations
for diagrams requiring less contrast and a series of diverse yet
soft colors for diagrams requiring more contrast. After messing
around a bit, I came up with a few potential color variants using
this theme. Please review the dark/light example for simple
diagrams [2] and the diverse color example for complex/contrasty
diagrams [3] and provide comments. For the first diagram, indicate
which of the controller node, network node, compute node, and
block storage node objects look the best (ignore the object
storage nodes). For the second diagram, indicate which of the
nodes (dark/light) and network colors look best. You can also
reject this theme completely. However, if you do, please provide
one or more suitable alternatives. I would like to upload a series
of revitalized diagrams to the installation guide as soon as
possible.
