The Color Sensor can make a competition robot better in the following ways: It lets the robot detect the color of an object near the sensor. This is useful if you want the robot to sort differently colored objects, drive up to a specifically colored object, or detect the color of objects as they pass by the sensor.Previously, I trained a YOLO model to detect the color (10 class of colors), but running 2 deep learning models is too slow for my real-time requirements.

RGB is a color code system, used in digital graphics and computing to represent colors. In RGB color code, each color is represented by an integer value ranging from 0 to 255 or a floating-point value ranging from 0.0 to 1.0. In RGB color code, each color is defined by its intensity of red, green, and blue light.

You should instead of it convert your RGB values to LCH system and extract C (=chroma) or to CIELAB system (=Lab in Photoshop) and calculate sqrt (a^2+b^2). Those systems are developed to be more linear in predicting what's seen. For grey C=0 and a=b=0.
