I really don’t know about the colors, but I had a friend from school who worked at a winery that did silk screen. Just be really sure you know how many bottles you will need. Too many and you’ve wasted a bunch of money, and too few and you will have left over juice- and reordering a small amount will be really expensive.
Not sure how it might apply to silk screen but my daughter, who’s been a brand manager and now a marketing exec for large wineries gave me some warnings when I was designing a label for my wine preservation device. She said to be careful with greens and darker red/burgundy colors. From my own experience, in the apparel industry, I found that to be true in a lot of applications. Part of the problem is color integrity and part is what happens when those colors are put over dark wine bottle glass colors. I can also tell you that, in t-shirt printing, you have to ‘flash’ or undercoat with white ink to get anything close to what your original color looks like when you print on dark grounds, or where dark grounds will show through. I would expect labels would be similar.
