That narrow width and low light definitely call for a careful balance. Since pastels felt dull for you, maybe try a mural with a mostly light or neutral background but with pops of brighter colors in the details - like delicate leaves or flowers with subtle shading. This can add interest without overwhelming the space. Abstract shapes in soft gradients might also keep it airy while giving a modern vibe. Also, consider a satin or eggshell finish paint for the mural - it reflects just enough light to add some glow without the harshness of gloss. If you want to add depth, a faint shadow effect behind some elements can create a subtle 3D feel that tricks the eye into perceiving more space. I’ve seen hallways feel much more inviting when the art has a bit of lightness and layering rather than flat boldness.
