This beautiful white lily stands out against its green leaves. Its delicate pedals are gently bowed back and the pistil in its center is a vibrant yellow. Its long, thin stem adds to its graceful beauty, and the unbloomed bud adds a hint of anticipation of what's to come. To bring out the richness of the colors, I suggest coloring the lily a pale yellow and shading the petals a light pink. The leaves could be a bright emerald green, and the stem a soft brown or olive hue. For the center of the flower, a golden yellow with white highlights would do the trick. Finishing off the piece with a hint of soft light blue on the background would give this stunning lily its final pop of color.
