Help Me Identify My High School (78-82) English Textbooks

Google has failed me (or I, it) in locating said books. (My search was: “High school English textbooks, 1970s, hardback, red, yellow, green”) These English textbooks were rather small (maybe four inches by six, but a couple inches thick), hardbacks, and came in a different color for each grade (9-12). Three colors I remember were yellow, red and green. The other may have been blue; it may not have been. I can’t remember.

Anyone from that era remember?

Could this be it?

No, they were solid bright colors with the title and editor on front, iirc. Thanks, anyway.

Maybe these? Looks like there’s a different color for every level and the cover designs have changed some over time. Size is 6 by 8 inches.

Sorry, no. No designs on the books. Solid bright colors with text.

Thanks all for trying.

A long shot, since it doesn’t really match your description, but maybe your memory is fuzzy or there were enough different editions that it’s worth a shot:

Warriner’s?
