+# Is Color Detected
+
+Checks the color is detected
+
+```sig
+let b = sensors.color1.isColorDetected(ColorSensorColor.Blue)
+```
+
+The [color](/reference/sensors/color) you choose to look for is one of the colors that the sensor can detect. If you want to use colors for tracking, it's best to use a color that is the same or very close to the ones the sensor detects.
+
+## Parameters
+
+* **color**: the [color](/reference/sensors/color) to watch for.
+
+## Example
+
+Wait for the sensor to see ``blue``. Then, show an expression on the screen.
+
+```blocks
+brick.showString("Waiting for blue", 1)
+while(!sensors.color1.isColorDetected(ColorSensorColor.Blue)) {
+    pause(20)
+}
+brick.clearScreen()
+brick.showImage(images.expressionsSick)
