ManyCam/Zoom coloring issue

I am using a video camera as an input in ManyCam. When I select the ManyCam virtual camera in Zoom, the coloring of the image from that camera is slightly different than (1) how it appears in ManyCam itself, and (2) how the feed from the video camera appears in Zoom if that camera is selected directly in Zoom, bypassing ManyCam. Why is this and can it be fixed? Thanks.
