I copy/pasted and blew it up and still only saw grey, so I added a yellow boarder to it and, wallah! Brown! I think that due to its size it is a little hard to see, but especially with the surrounding colors (the blue on the inside of the picture which amplifies the lights against the cityscape,washing some of its color out) play against the boarder color. However, if you place this picture on a lighter colored matte (especially in the yellow/red hue) it will counter the blue and draw out the brown a little more. IMHO. Then again... Que se yo?
