The below measurements are approximate:
For the lavender color, sizes smaller than 1/2" can look almost clear when viewed directly from the front, but are lavender in color when seen from different angles.
For the Foggy Gray, Plum Red, Lilac, Montana grape, Forest Green, Lapis Blue and Robins Egg Blue, the color varies through out each size. Some will have swirls, dark spot or translucent spots. All transparent colors will be more translucent in the smaller gauges.
