Latex includegraphics decodearray
The use of the decodearray option to \includegraphics allows the rendering colors to be changed.
The decodearray takes 6 parameters which is brightness, whiteness, and four
colors in CMYK color model, i.e., cyan, magenta, yellow, and key (black).
For instance, if you want a gray graph:
\includegraphics[decodearray={0 1 .5 .5 .5 .5}]{your_graph.jpg}
where 0 means no changes to the brightness, 1 means keeping the whiteness of all the colors, the four 0.5 means gradations of four colors from full to half saturation. Hence the four 0.5 make the graph to be gray.
