afaict, this is a limitation of the "particle API" used by Gem.
while the `pColor()` function (as used in `part_color.cpp:56`) has indeed an "alpha" value, this is only a scalar, and not part of the 3D(sic! there's now 4th dimension for the alpha) space that forms a domain.

** [bugs:#228] part_color ignores alpha component**
**Status:** open **OS:** any **Release:** unknown **Labels:** particles **Created:** Tue Aug 19, 2014 04:24 PM UTC by Anonymous **Last Updated:** Wed Aug 20, 2014 02:53 PM UTC **Owner:** nobody
Using Gem 0.93.3 on Windows 7 32bit.
I noticed that when using a part_color, the 4th value (alpha component) is ignored. I looked at the code, and I think it is line 56 of part_color.cpp. When rendering, the color is not passed into the function.
