Hello People,	

I would like to ask the follow question.

How can I overlap/merge two density plot (in attach) using gnuplot. One image is in red scale and the other is in green scale.

Density plot in red and green scale

In theses two images the lowest value is white (background) and the highest values are represented by pure red [ RGB (255,0,0) ] and green [ RGB (0,255,0) ] scale.


I looking for a way two overlap this two images, such that intersections are a combination of red and green to give a yellow intensity dependent on the "red" and "green" values.

In summary I need that resultant image had red, green and yellow colors.

I've tried some methods to interpolate the two images, but the resultant image is:

interpolation

I was expecting a light yellow [ RGB (255,255,0) ] color resultant but I get a dark yellow [ RGB (127,127,0) ]. How can I solve this problem using gnuplot.

The data files and gnuplot script for the red and green images are available in the link below

Thanks for attention.
