Symbols on California's Flag The once common California grizzly bear (also the official state animal) portrays strength; the star represents sovereignty; the red color signifies courage; and the white background stands for purity.
Today, the flag continues to carry the 13 red and white alternating stripes and now displays 50 white, 5-pointed stars against a blue background, representing the 50 states. Although the colors of the flag did not originally hold a specific meaning, many people have since suggested the significance of the colors. Red represents valor and strength, white represents innocence and purity, and blue represents perseverance and justice. These are the same meanings attributed to the colors of the Great Seal. Other people suggest that the stars symbolize the heavens and the stripes symbolize rays of sunlight.
