The set included four mixing bowls, which came in yellow, green, red and blue. As the earliest set released by Pyrex opal ware the new “Color Bowl Set” did not have standard model numbers such as 401, 402, 403 and 404 as we have come to know them today, but they are standard bowl sizes. They were redesigned in the 1950s to include numbers and sizes on the bottom of each bowl.
