Tomatoes ripening and are still yellow?

just so curiouswhy my 2 different tomatoe plants both ripened yellow?they were purchased from 2 different sellers they are 2 different type ..beefsteak and teardrop and both were tagged as a red variety...could it be from something in the soil????

That sounds like the tags got mixed up.I do love the taste of yellow tomatos.
