You are setting blue to average 2 times instead of setting red.

>For any pixel in the image, get the color: color = image.getPixel(x, y)
>calculating the average value of the rgb-values: average = (color.red +
>color.green + color.blue) / 3
>assigning this average value to the three channels:
>
> color.blue = average
> color.green = average
> color.blue = average
>
>setting the new color of the pixel:
>
> image.setPixel(x,y,color)
>
>and this for each pixel.

>This method worked on another project. Now it is not working. The resulting
>image is not entirely black and white, instead it is green and white.

>When I play with the values, I can change the colors, but the main error is,
>that it is not monochrome.
