I need the color detection/classification part to be very fast, preferably not using deep learning. Maybe pure Python or OpenCV or whatnot.color is meta-data. People need to understand that when they use color to differentiate cells. Excel has very limited capabilities of evaluating color. Even the human reader of the spreadsheet cannot tell why a cell is blue and another cell is green. It requires a legend, a system, a frame of reference.

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. Step3: Convert image to HSV color space. It is difficult to use RGB (BRG in OpenCV) color space for color detection due to variations in lighting conditions and complex relationships between the three channels (R, G, and B). For example, let’s say we want to find a red apple in an image that has a green background.
