Vibrant Abstract Painting That Features Three Geometric Shapes

Create a vibrant abstract painting that features three geometric shapes: a standout green triangle, a moderately sized orange triangle, and a purple triangle, all set against a pale gray backdrop. The green triangle should have a sleek, glossy appearance, while the orange and purple triangles should display a textured, painterly quality with visible brushwork. Arrange the shapes in a manner that conveys motion and balance throughout the composition.
