Mississippi's current flag, the In God We Trust flag, became official in January 2021 after voters approved it in November 2020. A white magnolia sits on a blue center panel, ringed by 20 white stars and a gold star, between gold and red bars. The law lists Pantone colors (200 C, 7563 C and 282 C); the hex values here are close screen matches.
These are commonly used reference values; they can vary by source, material or screen.
