Enigma in linea «Watching the evening»

The one who put P. 3 : "many parts of the puzzle do not differ visually, due to the fact that the picture has large areas (a third area and above) painted a solid color without the presence of graphic elements that allows at least approximately to locate them in the puzzle." Solid color is a solid color.Don't want to offend you,but the question suggests itself - do you like zlatoustie you distinguish shades of colors ? This is not my first puzzle,which isn't moderated for this reason.Gentlemen moderators,please,pay attention to it.
