Changing colour of brush images

I just did a rain cycle using the brush in a custom colour I made of a semi-opaque grey in the Drawing Layer and all the raindrops turned red after a few playbacks! Anyone know why and how I can turn them back to my custom colour?

I can’t answer this for sure, but it seems that when TBS can’t find a color for a drawing object it defaults to red as the applied color. This can be the result of the original color being deleted or the color palette being reset or things that go bump in the night -JK
