Hi,
I have a few options for you, depending on the space you have in front of the wall and your budget, they are-
Create (or get someone else to if DIY ain't your bag) a set of lit shelves with a perspex covering (doors or drawer fronts), you can decide the depth of the shelves to suit the space you have and if you had the room you could incorporate a hanging rail. This would provide storage, soften the area and if positioned well the lights would bighten the area wthout being block by things you can store in/on the cupboard/ shelves. (You can use fairy lights from the mains and just rest them over the shelves, have lights fitted for a stronger light or use 'slap on' lights, jml do them as do most diy stores- again what you you chose to do depends on your budget)
A second, less expensive option would be to paint the wall a shade of white (to compliment your decor) in a semi gloss and randomly hang (plain or clip frames) photos that have been printed in bright colours on it.
