It depends upon what you mean by predominant color.
If the image is 24-bit color, then you have real trouble as there are
millions of colors and finding a single predominant color is not easy.
However, you can reduce the image down to a single pixel and get the
color of that pixel. For example
convert rose: -resize 1x1 miff:- | convert - -format
"rgb(%[fx:int(255*u.p{0,0}.r)],%[fx:int(255*u.p{0,0}.g)],%[fx:int(255*u.p{0,0}.b)])"
info:
Or you may quantize the colors of the image to a reasonable number
and then look at the histogram to find the most frequently used
color. See -colors
