A flag featuring a central, large sun, radiating outwards, in shades of gold and orange. The sun is set against a white background. In each corner, a single, five-pointed red star is placed. The overall design is bordered by a thin, dark blue stripe. The red stars and blue border are subtly shaded to create depth and a sense of three-dimensionality. The color palette is predominantly white, red, and blue, reflecting the specified color scheme. The design evokes a sense of unity and national pride, inspired by the union of Panama and Costa Rica, with the sun symbolizing a shared bright future and the stars representing the key elements or regions of the combined entity. The flag's proportions are optimized for clear visibility and balanced aesthetics.
