Reflected Light Intensity Mode: measures the light intensity reflected off the surface of an object.Ambient Light Intensity Mode: measures the light being emitted from an external source (e.g.Color Mode: Reads up to seven colors (plus it can detect the absence of color).There are three main modes within the color sensor programming block: The EV3 Color Sensor assigns a numeric value to each color it recognises, the table below lists all these values (or color IDs): Color In color mode the LED lamp emits red, green and blue light and uses the color sensor to determine any one of seven colors (black, blue, green, yellow, red, white, brown), it will also detect no color. It will output a numeric value based on the intensity of the light between 0 (very dark) and 100 (very light). In Ambient Light Intensity mode the color sensor will measure the strength of light that hits the color sensor. Using a scale from 0 (very dark) to 100 (very light), the sensor will assign a number to the intensity reading. In Reflected Light Intensity mode, the EV3 Color Sensor will emit a red light from the LED lamp and measure the intensity of light reflected back into the color sensor.
