Bean seed ID help

Lidl sold a bean called Wachs beste von Allen https://deaflora.de/Shop/Bohnen/Buschboh...Allen.html
I had some in last year's random swap. Maybe you bought them in Lidl? Supposed to have yellow pods.

Looks promising but don't recollect buying them.  I wonder if they're yin yng that didn't make enough black colouration. Or even cherokee trail of tears gone white, they're about the same size. No matter they're a bean , they'll get sown  or eaten
