I posted a few pictures of this one already, but here are a few more in natural lighting
with a few white pieces of paper for color comparison.
Edit to add my thoughts behind the design:
The choices of materials and colors capture my notion of a practical “steampunk” or Victorian era design. The wooden (walnut) case and brass plate are meant to reflect choices that might be made in an age before plastics and affordable aluminum. While the keys are actually made of PBT, the specific color and smoothness of the finish are meant to imitate ivory. Of course, various internal parts (switches, PCB, foam) consist of post-Victorian materials, but one can suspend disbelief about how it actually works and what those are made of.
