Thank you so much for replies!
Teri.p , i am afraid i am still too unprofessional for enamels.. but the color looks very attractive
yellowbird, yes, images of "copper blue" on google looks exactly what i want
electric avenue is not transparent color.. Now those old beads have very uneven surface, but still they should be considered as transparent, or, i should say, they WERE transparent before.
MelanieG, by diluting, you mean making transparent bead and then adding this intense blue on top?
Lyssa, i am so glad there are people here who make replicas
i wrote to you on facebook (i hope that was you, not sure yet
).
For second bead i will have to try dark aqua and see how it will look.
