June 27, 2008: Response for the new sizes has been amazing. I've been shipping them out just as fast as I can anodize them, and now I've run into supply problems. You can continue to order all the colors in all the sizes, but if the order button is red it means that size/color will go on backorder and I'll ship it in a couple months. I'll post a specific date as soon as I know. May 7, 2008: The new sizes are here! If you're looking for size "small" I'm now calling it 6:20nb. Size "large" has become 8:20nb. color 20 gauge rings $34.33/troy ounce 18 gauge rings $25.30/troy ounce 16 gauge rings $20.79/troy ounce Color #0: Unanodized niobium. Shiny medium grey. Looks a little like stainless steel. Color #5: Nearly the same as color #0, but a tad warmer. I include it for completeness' sake. Color #10: Milk chocolate. Color #15: Coffee brown, sometimes with a little plum shimmer around the edges. Color #20: Midnight blue or deep eggplant, depending on the anodizer's mood that day. If you need it to be blue, get color #25 instead. Color #25: Navy blue. Pretty consistent color. Color #30: Light blue. Color #35: Ice blue. Color #40: I try to get this one right on the blue/yellow border. Like color #35, but warmer. Color #45: Pale yellow. Color #50: Bright yellow. Pretty consistent color. Color #55: Warmer than color #50, more of a golden-orangey color. Sometimes has shades of pink around the edges. Color #60: Salmon pink, sometimes with an apricot shimmer. Color #65: On the pink/purple border, I think of this one as "fuchsia." Usually more pink than the sample picture shows. Color #70: "Royal purple" is my target for this one, but it varies by batch. The sample picture looks much more teal than the target rings look in person. This purple-through-teal range (#65 - #80) is tricky to photograph. Color #75: Iridescent purple/teal. The most variable color - some batches are closer to purple, some closer to teal, but all will have some color crossover. Individual rings within a batch may vary, though I try to pick those out. This color is a headache, but it's worth it - my personal favorite! Color #80: Teal. Very rarely there might be a tad of purple hint around the edges, but this is usually a reliable color. Color #85: Grass green. Color #90: Lime green. Usually has a few troublemaker rings that are closer to either #85 or #95 (or both!). When the voltage is this high color gets hard to control, but I try to pick out the worst of the off-color rings. Color #95: Peach? Lime? Tan? Very odd color, and often tricky to get. You'll probably find some troublemaker rings that are closer to color #90, though I try to pick out the worst of the offenders.
