60s vintage lamp parts, colored plastic 'stained glass' fruit

Lot of vintage colored plastic disks for a 60s hanging light. These must be really nice when back-lit by the light, colors are true red, lemon yellow and deep blue.

These are 2 1/2" in diameter, rigid plastic with a molded curve shape. All have fruit designs.

There are five of the blue, five of the yellow, and four of the red.
