"Flowers 花卉" by Tang Yunyu is a pastel work on blue paper that showcases the artist's approach to floral subject matter through the vibrant and immediate medium of pastel. The choice of blue paper as a ground creates a cohesive chromatic foundation that likely complements the delicate or bold treatment of the flowers rendered in pastel. This composition demonstrates the versatility of pastel as a medium for capturing botanical subjects with both precision and expressive color.
