Add Contrasting Vertical Decorative Elements

What happens here

Enhance the visual appeal of the wall by adding thin, light brown (or wood-look) vertical decorative strips. These strips are interspersed between the darker gray composite planks, creating contrast and adding texture. They appear to be either inserted into pre-made grooves or carefully fastened to the existing wall structure with small, discreet fasteners or adhesive.

Goal: Introduce contrasting elements to the wall's design for added texture and visual interest.
