Some examples of differences are shown here. Only in a handful of cases were the exact same colors used in more than one pattern. Knowing the differences is important to the collector, lest a piece is purchased thinking it a match to a particular pattern, only to later find otherwise. When viewed alone, some shades might appear indistinguishable from others until both are seen side by side. Subtle differences exist in shades of color from one pattern to another.

BLUE PYREX SERIES
The shades of yellow on the 400 series mixing bowls from the original multi-color, the all-yellow set, and both the Town & Country and the Daisy pattern collections are all noticeably different.The exact shades of the green 403 and blue 401 primary color mixing bowls also varied slightly over time.The shades of the original orange-red 402 mixing bowl, the later red 402, the red 402 from the Friendship pattern collection, and the red-orange 402 from the 1968 new multi-color 400 set are all slightly different.Primary color mixing bowls were described in early advertising as Canary Yellow, Jade Green, Chinese Red, and Robin Egg Blue.Avocados and harvest golds continued in Spring Blossom Green and Butterfly Gold, respectively, In the 1970s, the bright colors of the late 1960s continued with Friendship, but gave way to earthtones and rustic shades in the latter half of the decade. The popularity of avocado greens in the late '60s was reflected in Verde.

The 1960s first brought warmer tones and pastels like Sandalwood and Early American, suceeded later in the decade by the brighter colors of Daisy. The 1950s were rounded out by turquoise, pink, and pale yellow. The cheerful early primary colors of the 1940s were soon joined, albeit briefly, by lime green and flamingo pink. Over the years, the colors offered were reflections of the tastes of the times. It all began with the iconic primary-colored set of four mixing bowls in yellow, green, red, and blue, and took off from there. While Pyrex ovenware in clear glass had been massively successful for nearly 30 years, it was the introduction of the color ware in the 1940s that cemented its place in kitchenware history.
