Suggestion:
More information on your specific likes and dislikes would be very helpful here. Do you like the rounded, bulbous look of '50s appliances? Do you prefer the "space age" sleekness of '60s units? And what about function - do you prefer gas or electric? Is a self-cleaning oven important to you?
For all-around reliability and repairability, General Electric ranges are a very viable choice, and they came in the colors you're interested in for over ten years, in both '50s and '60s versions. Beginning in the Fall of 1963, GE was the first appliance manufacturer to offer self-cleaning ovens.
Frigidaire ranges are high-quality units as well, but General Motors sold Frigidaire to White Consolidated Industries (now Electrolux) in the late 1970s, with the result that parts for GM-built units can sometimes be a little harder to come by. Range burners and their supports are a bit of a challenge sometimes.
Anyway, you will get to your goal faster if you say, "I want a so-and-so." Deciding what's right for you will help speed things up.
