I've got ECCO Soft Sneaker in Marigold leather for the same reason - was 60% and looked so sunny-cute-joyful. Haven't worn them yet.
Mostly same plan for outfits: black and white printed pieces, basic black and navy pants, grey jeans. Nothing in yellow except a fav BR leather bracelet and maybe one printed top ( mix of blue/red/yellow and white ).
Hope you will post a pic or two of outfits with sunny sneakers .
