That sounds intriguing, but make sure you keep the physics in mind—black holes don’t actually “glow,” they just warp light around them. Maybe start with a dark canvas, use a gradient of deep blues and violets for the accretion disc, then layer a translucent, reflective medium for the event horizon. A subtle glow-in-the-dark could hint at the Hawking radiation, but keep it faint; otherwise it feels too literal. If you can capture that invisible pull with motion—perhaps a slight swirling of the paint or light flicker—it will give the piece that cosmic tension. Try it out, and we can tweak the narrative once you have the first draft.
