Color Sensor RGB Block

The Color Sensor RGB Block uses the standard LEGO® MINDSTORMS® EV3 Color Sensor to measure color using RGB color values. You can use this block to detect colors other than the standard LEGO brick colors that are supported by the Measure - Color mode of the standard Color Sensor Block.

This block was created by David Gilday for MindCub3r, the EV3 Rubik's Cube® solver robot.

Note: this block may not work as intended with some versions of the EV3 firmware. Please see the MindCuber website for more details.

Modes

Measure - RGB color

This mode returns the Red, Green and Blue components of the RGB color.

Parameters

Port, Red, Green, Blue

Set Port to match input port on the EV3 to which the Color Sensor is connected.

Use Red, Green and Blue to read the values of the three color components from the measured RGB color. Each value is in the range 0 thru 255 indicating how much of the color component is present in the measured color. The larger the number, the more of that component is present.
