Create a watercolor and gouache artwork with color splashes, depicting a 23-year-old Portuguese man with fair skin and long, straight purple hair. The focus should be a close-up of his face from a frontal view. Use the lightness and fluidity of watercolor to craft a soft background, paired with the intensity and vibrancy of gouache to highlight his facial features and purple hair. Add dynamic splashes of color to infuse energy into the composition, creating a vibrant contrast that emphasizes the uniqueness of the portrait.
