Conway Stewart Colors

I realize there may be some variability within specific series and model CS pens but, in general, which color is generally considered to be the more coveted / valuable?????
Black Cracked Ice or Tiger Eye

Thanks for any thoughts.............

While I find many of the Conway Stewart celluloid pens:crazy_pilot: colorful and interesting nothing comes close to the subtle sexiness of a 60L in Herringbone....any color!
