Accepted answer
you can use openCV

Hey Smitha, you could use OpenCV only because in my experience i have faced issues as i have used other API then later i used back OpenCV only because i was i need of this to implement some otherthing so thing is to avoid use of multi API.

in python as well you can create a library by yourself
look at this example , the small piece of code

without library this is my code, which should work
using System.Drawing
public static Color getDominantColor(string path)
        {

            Bitmap bmp = Bitmap.FromFile(path) as Bitmap;
            //Used for tally
            int r = 0;
            int g = 0;
            int b = 0;

            int total = 0;

            for (int x = 0; x < bmp.Width; x++)
            {
                for (int y = 0; y < bmp.Height; y++)
                {
                    Color clr = bmp.GetPixel(x, y);

                    r += clr.R;
                    g += clr.G;
                    b += clr.B;

                    total++;
                }
            }

            //Calculate average
            r /= total;
            g /= total;
            b /= total;

            return Color.FromArgb(r, g, b);
        }

Yes thats popular API thats the reason know that also that API has many functionalities. if want you can use Dataweave API its also open source i have not used yet.
