Colorama was made by Homer Laughlin China for a short time in the 1960s. The flatware is the same generic plain round coupe shape used for many lines of the time.
However, the hollowware is unique. The sugar and creamer were made with a stretched look and pinched necks. The finial for the sugar lid is reminiscent of those used in the older Swing shape.
The 10" dinner plates are often marked with one of two different Colorama/Homer Laughlin backstamps. Unfortunately, both styles of marking lack a date code. Expect to find all other pieces unmarked.
At least two different solid color glazes were used on Colorama; orange and a pastel blue. Other colors may exist.
