Hi,
My recommendation here is simplicity, which you also pointed out in your brief.
I want to take this in direction of IKEA, ASKO and similar brands were we have no actual imagery, but only the word... in a special colour or as here... mounted on a coloured back plate that lifts the wording.
Du kan prata svenska med mig om du så önskar..om det underlättar ;-)
Mvh/Regards
