The four shot glasses pictured display an iridescent glass effect which is characterized by its shimmering, multi-colored appearance that changes with the angle of light.
Explanation:
Iridescence is a phenomenon where a surface appears to gradually change color as the angle of view or illumination changes.
Iridescent glass achieves this effect through various methods, such as applying a thin food safe coating during manufacturing or by creating micro-structures on the glass surface that interfere with how light reflects.

The glasses in the image exhibit this characteristic rainbow-like sheen, reflecting hues of pink, purple, blue, and yellow, which is a hallmark of iridescent glass.

Finding such glasses isn't always easy especially since they are mid century modern.
