Zachary is what some people call baby blue, but it can also be called a very pale periwinkle. When you compare regular Periwinkle with Zachary, Zachary is 50% lighter than Periwinkle. I like the results I got by pairing Zachary with Cranberry Pink (used in the form of a rose cane), with a little goldstone ribbon thrown in the mix for some flash.
The Great Bluedini kind of looks like a transparent version of Mermaid and could be describe as a rich dense blue-green. In fact when you pair Great Bluedini with Mermaid, it makes both colors pop. I made a white heart out of Great Bluedini and decorated it with roses out of Cranberry Pink and some goldstone ribbon, with good results.
To see how Great Bluedini worked as a core color, I made a dichroic covered heart pendant with a core of Great Bluedini and I really like how it came out. I tried several more beads out of Zachary and Great Bluedini to show how these colors look in different arrangements and you can view them below.
