Two pink and white tulips with closed and open petals against black background.

Photorealistic botanical study of two Tulipa specimens displaying bicolor morphology. Left specimen shows closed form with pink outer tepals gradually transitioning to white at petal margins, accompanied by yellow basal coloration. Right specimen exhibits expanded form revealing interior stamen structure with green-brown reproductive organs. Both specimens mounted on green stems with measured stem angles diverging approximately 30 degrees. Lighting technique employs directional illumination creating defined shadow gradation across petal surfaces, emphasizing textural striations and cellular structure visible through translucent petal tissue.
