+There's a bug in the firmware which prevents you from deleting the programs (``*.uf2`` files) from your EV3 Brick. There isn't a firmware update to fix this yet.

+We have prepared a special program that lets you delete UF2 files from the brick.

+Checks the color is detected

+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
