The Pixel condition checks the color of a specified pixel on the screen. The location is defined by the X and Y coordinate relative to the top left corner of the main screen.
As with all numeric fields, the numbers can be calculations including functions, and the fields expand to allow for longer expressions as soon as you type something other than a number.
You can test if a pixel:
is or is not a specified color (within 10% of red, green and blue).
is brighter or darker than a specified color.
is more or less red than a specified color.
is more or less green than a specified color.
is more or less blue than a specified color.
