Colour Detect
Description
The Colour Detect component finds the areas in an image that match a particular colour. 
A colour range in HSV (Hue/Saturation/Value) format is used to define the regions of interest. You provide a lower and upper HSV. The 
algorithm will check the H,S and V components of pixels in the image against the upper and lower ranges for each component. H is in the 
range 0-360, S and V are in the range 0-255. An example input would be “360,255,255”.
The MinArea input allows you to specify a threshold for discarding detected areas based on their size. This input is an area in pixels
