If so, this does it:

get your rgb image (image 1)
duplicate it (image 2)
convert it to greyscale
apply  a sepia LUT
convert back to RGB
average image 1 and image 2
if you want more subtle colours, average this result again with image 2.
adjust brightness/contrast

As a macro:
//------
//run("Mandrill (70K)");
a=getTitle();
run("Duplicate...", "title=Image2");
run("8-bit");
run("sepia"); //sepia LUT
run("RGB Color");
imageCalculator("Average create", a,"Image2");
run("Enhance Contrast", "saturated=0.1");
run("Apply LUT");
//------

Gabriel
