Declaring ofColor key in multimap

hi,

i am trying to use ofColor as a key in a multimap, but receive an "invalid operands to binary expression" error although i am not comparing values and have no need to overload an operand.

.h:

multimap<ofColor, string> colorMap;
multimap<ofColor, string>::iterator colorMapIt;

.cpp:

colorMap.insert(make_pair(ofColor(random(255)), "null"));

i tried creating a class to handle the ofColor and used that class in my multimap declaration, but the error was still the same.

any ideas?

thanks in advance.
