thank you!

I am making an OpenCV program that is able to detect 10 different colors and be able to differentiate between them. What are 10 different colors that OpenCV is able to detect easily?

How limited is OpenCV in detecting colors? If 8-bit colors are used, how many colors can OpenCV detect easily?

@Tina123 added the output image to the post above.

From the image below, I want the input (left image) to have an output (right image).

I've tried adaptive threshold, canny, skin detection, blurring, dilating and eroding, finding contours then floodfilling it, and approxPolyDP but still can't get the right output. I can not floodfill right because there are many contours. what am I doing wrong?

Here's a sample of the SkinDetection code:

#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
Mat src;
int main(){
    src = imread("open_1a.jpg");
    if (src.empty())
        return -1;
    blur( src, src, Size(3,3) );
    Mat hsv;
    cvtColor(src, hsv, CV_BGR2HSV);
    Mat bw;
    //inRange(hsv, Scalar(0, 40, 60), Scalar(20, 150, 255), bw);
    inRange(hsv, Scalar(0, 10, 60), Scalar(20, 150, 255), bw);
    imshow("src", src);
    imshow("dst", bw);
    waitKey(0);
    return 0;
}

here's the input and the output of the code above:
