Hello devs can anyone know how How To decide which colour is to be removed in the background of video in javascript ?.

right now i only remove the green background

                let red = frame.data[i * 4 + 0];
                let green = frame.data[i * 4 + 1];
                let blue = frame.data[i * 4 + 2];
                const colorToRemove = green;
                if ( colorToRemove > red && colorToRemove > blue && colorToRemove > 200){ 
                    frame.data[i * 4 + 3] = 0;
                }

i use canvas here. the frame.data is rgba pixel value return from canvasContext.getImageData()
