Whats the difference among these shades of red colour?
Sorry argue with someone named Robin about shades of red (well, my mother’s name was Rose), but I think it’s crimson that has a slight blue or purplish cast (think of beets) and scarlet that’s slightly orange (very ripe tomatoes). The American Heritage Dictionary defines “carmine” as “a strong,to vivid red” or “a crimson pigment derived from cochineal” and “cardinal” as “a dark to deep or vivid red.” It seems to me that these shades overlap quite a bit, but for what it’s worth, descriptions of the setts of Scottish tartans use “red” for the clear red of tartans like Royal Stuart and “crimson” for the purplish red of tartans like Lindsay.
