Positioned at various depths against a pitch-black background, these beautiful flowers stand out in stunning profile detail of their large petals. The darkest parts of the petals are near the base, gradually lightening to a warm yellow as they grow towards their delicate ruffled edges. Delicate, curving light-colored lines ripple along their centers, creating an elegant juxtaposition with their bold centers. In the center of each flower is the bright yellow stamen that protrudes slightly from the fragile, light-colored pistil. To the sides, the leaves are long, skinny, and a deep, mysterious green with sharply-toothed edges.
I would advise a two-toned coloring style for this image. Start by filling in the different petals in a warm yellow, with the deeper yellows along the base of the petals, and a softer yellow towards the edges. Then, shade the petals with lighter yellow and orange tones, to bring out the vertical lines running through the flower. Follow this with a deep emerald or deep blue-green for the leaves, with a lighter blue-green to further emphasize the edges. The background could be filled with a variety of dark, cool tones to make the flowers stand out. If desired, a light purplish hue on deeper sections of the flower and background could be added to create contrast and nuances.
