Create a vertical 4:5 two-color underground editorial poster printed on intensely saturated electric-blue paper. Place two simplified human figures seated face to face in the center of the composition. On the left, show a completely warm-white figure sitting upright on a thin round stool. Render the body as a flat featureless silhouette with only minimal electric-blue marks defining the arm, legs and clothing folds. Surround the head with a circular burst of thin white rays. Print a tiny text: “AN IDEA IS ONLY A SPARK.” On the right, show a completely electric-blue figure seated on a rough white rectangular crate, leaning slightly forward toward the other figure. Surround the entire body with a tall vertical field of wild warm-white flames. Add a smaller burst of white rays emerging from the figure’s chest, representing sustained obsession. Print a tiny text: “OBSESSION KEEPS IT BURNING.” Keep the figures close enough to suggest an intense private conversation, but do not let them touch. Use no facial features or realistic anatomy.
