The most common color is marigold, followed by amethyst/purple, blue, and green.

To check the color of the piece, use a strong light and look through it at a place where there is no iridescence. With a bowl or plate with heavy iridescence, you may have to look through the edge of the collar, or marie, on the bottom.

Shown here are Ripple vases in aqua, purple, clambroth, helios, marigold, smoke, and amber.
