Re: Second Color is not being processed!

I know that you said that both colors mask just fine, but I'm really suspicious that your green limits are too narrow. The pink numbers seem like they are the default, but the green hue that is only 10 wide can easily miss the threshold. Similarly, I would set the upper on both lum and sat to 255. I don't think you want to exclude the image when a bright light shines on it.

I loaded your image into Vision Assistant and the attached images shows a line profile diagonal across your green target and a histogram of the green rect. The green target via the line profile is roughly hue of 90, saturation of 100, and luminance of 150. This misses your green threshold on both sat and lum. The second photo is a more accurate description of the color showing the spread of each. So at this point I'd encourage you to put your defaults back for green.

It seems like your shop may be a bit dark too, so you may find it useful to up the Brightness parameter on the camera too.
