I love how you’ve organized the data, it reads like a tidy gallery wall. The crimson for Baroque works is a solid choice—it captures the drama, though a slightly richer burgundy might highlight those chiaroscuro moments better. The muted greys for Minimalism are fine, but I’d suggest a touch of slate instead of pure charcoal, to give a hint of depth without losing that austere feel. Also, consider adding a light sepia for Romanticism—just a whisper that nods to the period’s softer light. Overall, it’s clean, but a few hue tweaks could make the visual narrative pop.
