We are supposed to use light and shadow, high key and low key, for this last week of Flash of Red.
Here is a focus-stacked sea shell, from our Turks and Caicos trip last May. In real life, it is a gentle pink and white. It looks rather austere here, but the textures seem to show up well.

I grew up with sea urchins (to eat and to collect on the beach!). The dramatic contrast of the shell's textures shows up even better on black. I wonder if you might have another version with more background on it?
