The flag of Puerto Rico has five horizontal stripes, red and white, and a blue triangle with a white star. The shade of blue has changed over time: the original 1895 version used a light blue, and for decades a darker one was used, so there is no single accepted value. Red is popularly linked to the blood of patriots and white to freedom. The HEX codes are commonly used reference values.
These are commonly used reference values; they can vary by source, material or screen.
