Yellow. Scratches on color, interior, and utensil marks. Wear on the rim. No chips, no cracks. Primary Colors is one of the "Holy Grails" for Pyrex Collectors. So charming!

Based on the markings on the bottom, I'm dating this as part of a 1040s-era Primary Colors set The markings on the bottoms of the 1940s ‘non-numbered’ bowls are only ‘T.M. REG.’ in an arch above ‘PYREX’ horizontally in the middle, and ‘U.S. PAT. OFF’ below in an up-facing arch..
