Need recommendation for a dark sound interconnects

I am interested to know which XLR interconnects, brand and model, have a tendency toward a dark sounding, or simply have a dark sound, that I believe need to use in my audio system between the preamplifier and the power amplifier in order to make the sound right. I know there are hundreds of brands and models of interconnects, but no manufacturer says that theirs sound dark or darker. If you have ever experienced such sounding interconnects XLR terminated, please let me know details. I have tried several interconnects lately, but all of them seemed to have a tendency for brightness as opposed to darkness. Right now I am using one pair of Discovery Signature XLR 1M interconnects, that partially helped. However, I would still want to try something different, with a dark sound.
