@sturkmen72 Why do you need *.png update? The original and new images look similar.

[sturkmen72]

updated files has alpha channel.
to make the test code more meaningful

    if (m_img.channels() == 3)
    {
        Vec3b vec;

        //Checking the first quadrant (with supposed red)
        vec = m_img.at<Vec3b>(2, 2); //some point inside the square
        EXPECT_LE(vec.val[0], colorThresholdLow);
        EXPECT_LE(vec.val[1], colorThresholdLow);
        EXPECT_GE(vec.val[2], colorThresholdHigh);

        //Checking the second quadrant (with supposed green)
        vec = m_img.at<Vec3b>(2, 7);  //some point inside the square
        EXPECT_LE(vec.val[0], colorThresholdLow);
        EXPECT_GE(vec.val[1], colorThresholdHigh);
        EXPECT_LE(vec.val[2], colorThresholdLow);

        //Checking the third quadrant (with supposed blue)
        vec = m_img.at<Vec3b>(7, 2);  //some point inside the square
        EXPECT_GE(vec.val[0], colorThresholdHigh);
        EXPECT_LE(vec.val[1], colorThresholdLow);
        EXPECT_LE(vec.val[2], colorThresholdLow);
    }
    else
    {
        Vec4b vec;

        //Checking the first quadrant (with supposed red)
        vec = m_img.at<Vec4b>(2, 2); //some point inside the square
        EXPECT_LE(vec.val[0], colorThresholdLow);
        EXPECT_LE(vec.val[1], colorThresholdLow);
        EXPECT_GE(vec.val[2], colorThresholdHigh);
