Can only get the grayscale image

[yulan0215]

When I launch the launch file and show in the RViz, the image is grayscale instead of RGB, can anyone give me an idea whether is it the driver problem or? Thanks

Try running rqt_image_view, if the image shown there is RGB, then it's likely an RViz bug or something.

Actually I ran the avt_vimba_camera for melodic(it is another folder in Github),and my camera is Mono-camera, when I ran mono_camera_nodelet.launch in this path, it is grayscale image even if I ran ROSRUN_NAMESPACE=camera rosrun image_proc image_proc, it made no sense. Can u tell me what is the problem?
