The MF website has the Gold and Chartreuse shad listed under the Bleeding liquid colors. That said; I think Ctom is correct in that they are a blend of a powder pearl. Unfortunately it appears they mixed them with a bleeding liquid color. I would opt to create my own from a pearl and a non-bleed liquid. The Chartreuse shad should not be a big challenge. The gold shad looks to have their gold pearl powder as a base.
