Detect color at a single Point

Color Detection is pretty much the same as Image Detection.

Rather than searching for an image in Region, we check for a color at a single Point.

Where to detect color. This is no different than a Point in a Click or Swipe

It's recommended to use the coordinates from the Color Picker

When doing color detection. We use a different metric to compare color. It's called delta E.

Delta E (dE) is a metric for understanding how the human eye perceives color difference.

Lower dE figures indicate greater accuracy, while high dE levels indicate a significant mismatch.

In most case, colors look the same with dE < 10. Identical colors will have dE = 0.

Alpha channel (transparency) is not a color property and most device doesn't capture the alpha channel, but if you need it you can enable the Include Alpha Channel option to include it in the algorithm.

    // Get color at point 500, 200
    var color = Color.get(Point(500, 200))

    // Compare color
    if (color and color.isSame("#FFRRGGBB")) {
        // Same color
    } else {
        // Different color
    }
