Was the particle color change alpha setting removed?
I do not see the option to change the alpha of particles anymore once GS switched over to the different color selector.

The only way I know of to change the Alpha of a particle color is to click the color selector box and then you can access the R, G, B and Alpha values of the color from the color wheel.
@myke66, @jamie_c, though the alpha only seems to work if you have assigned an image to the particles.
The default square seems to ignore the alpha setting. Don't know if this has always been?
@myke66, here is a screen shot.
@Hopscotch, I've heard that recently but have not tested it yet. I thought it used to work without images, but things tend to change...

@jamie_c It looks like it may have been removed with the new windows color selector..
