This activity returns an array of Color objects. Each Color in the array corresponds to the color of a pixel from the input image.
The input can be either an Image object, or the path to an image file as a String. If a UI element in a Citrix environment is color coded (a button that changes color when a file is ready for download, red/black text designating credits/debits, etc.), this activity can be used to iterate through on screen pixels and detect that color by passing a screenshot of the current display as input.
