Why is the picture black and white?

Question

C++ / C#

Hi all..

string filename = " Image4.jpg";

    Mat img = imread(filename, 0);
    cvNamedWindow("original");
    cv::imshow("original", img);

I'm new to OpenCv and don't understand why the image is shown in black and white even though it's in color.
And how do you color it?
Thanks for the help.

pass CV_LOAD_IMAGE_ANYDEPTH as the second parameter
