I know this year, as a part of Balloonacy, we released:
Nightsky - Black with silver sparkle
Goldenair - Creamy white gold with gold sparkle
Mint & Olive - Forest green with golden olive sparkle
Iris Accents - Light purple with silver sparkle
and last year along with Sweetie Cake we had (taken from Specktra.net's Color Stories):
Ultra-Chill - Pale mint green with silver pearl
Peacocked - Rich turquoise green with silver pearl
Nightsky - True black with silver pearl
Iris Accents - Violet with silver pearl
Reflecto - Mid-Tone blue with silver pearl
Not sure about collections before this though.
