Hello,

First, write a little player client that will connect to the
blobfinder interface. Have this client print out any and all blobs
that are detected.

If none are detected, then your color.txt file is most likely
non-optimal. I  ^think^ that the cmvsion sources has a gui that will
enable you to create a new color.txt file.
