to be exact, BAL made 3 magentas
05: pinkest RH only, no PT
07 (limited

RH,GGH and GSH.city only (maybe first too, not sure), paler pink and little bit of purple
08: paler than 07 but no purple shade, RH, GSH,GGH, all style (including PT)
T&D had several runs for magenta, but some vary to be 05 and some to be limited magenta.
in my opinion, they got the amethyst quite right and i will say it is amethyst without a doubt to anyone (even those who own real amethyst).
you can say this T&D amethyst is either LE magenta or amethyst, but not 05 or 08 pale magenta.
