Imagine an autumn-inspired nail art design for Color Street nails, where the essence of falling leaves is captured across each fingertip. Start with a gradient base that transitions from a warm golden hue, reminiscent of the setting sun, to a rich crimson of freshly-fallen leaves. Add delicate accents of metallic gold, mimicking the first frost's morning glimmer. Incorporate intricate leaf and vine motifs to bring a touch of elegance and nature. Complete the look with a glossy top coat for added depth and brilliance.
