I'm checking the myriaCross Floss list and don't see it there as an independent entity. However, I even if I find the colors, I can't tell. Your link does not work. I just get a 404 out of it.
Light Effects Fluorescent Collection Floss Pack (Art. LTE317WPK3) which has Tropical Pink (E1010)* Neon Yellow (E980) Bright Orange (E1020)* Electric Blue (E1040)* Luminous Lavender (1050)* Neon Green (E990) The * ones are the ones I was using
myriaCross Floss lists E980 and E990 but not the others. PCStitch 10 has DMC Light Effects but only the E980 and E990 of the Fluorescent colors. PCStitch 9 also has the same palette.
You can create them on your own if you can work out the actual color with the Floss Editor.
