How does the HSV system work? Everything i've looked at says H is an angle with 360 values?

If you are using OpenCV in the backend (like we do in all our HSV-related modules), their range is 0...180 and hues as follows:

0=red/do not use because of wraparound, 30=yellow, 45=light green, 60=green, 75=green cyan, 90=cyan, 105=light blue, 120=blue, 135=purple, 150=pink

Usually you would start in the inventor with widening the double-cursor slider to the full range. Then bring one cursor towards the center until you start losing your objects, then back a bit. Finally same for the second cursor. You may want to first also widen the saturation and value sliders too, then try to narrow down all three ranges in sequence.
