Interestingly, in Australia, major supermarket chain Woolworths used to have two parallel home brands: the bargain-basement Homebrand in stark black & white packaging, and the slightly better but still "designed in the DDR in the 1970s" Essentials. They had to ditch Homebrand, because it looked too cheap and was driving people to discount grocer Aldi, where you could get similar goods in packaging you wouldn't be ash…
Tesco, in the UK, did this too but only recently. They used to have a 'basics' range with labelling that said nothing but 'cheap'! Instead, they now have these wholesome-sounding brands such as Redmere Farms, Nightingale Farms, etc which imply you're buying from some twee family business instead.

They also have "Stockwell & Co" for the things which don't come from British farms, like jam and baked beans. That at least is a nod to history, because Tesco started out selling tea packaged by T. E. Stockwell.
They are entirely upfront about their brands:
