I agree with lexusChris. My personal experience though, is that carared and c20 have 1 difference. c20 has a more brown color and carared has a well....red color. the "darkness" or lovibond may be the same, but the hue in my experience is quite different. I use carared to add a bit of color and sweetness to my saisons, it really puts an emphasis on the intense orange color.
