Official color: BCC Dictionary of Colour Standards, No. 196. Also known as U.N. Blue.

The two narrow stripes
One represents "the flow of tourists to sun-drenched Aruba, enriching the island as well as vacationers", the other "industry, all the minerals (gold and phosphates in the past, petroleum in the early 20th century)". In addition to sun, gold, and abundance, the yellow is also said to represent wanglo flowers.
Official color: BCC Dictionary of Colour Standards, No. 113. Also known as Bunting Yellow.

The star
It is vexillologically unusual in having four points, representing the four cardinal directions. These refer in turn to the many countries of origin of the people of Aruba. They also represent the four main languages of Aruba: Papiamento, Spanish, English, and Dutch. The star also represents the island itself: a land of often red soil bordered by white beaches in a blue sea. The red also represents blood shed by Arubans during war, past Indian inhabitants, patriotic love, and Brazil wood. The white also represents purity and honesty.
Official color: BCC Dictionary of Colour Standards, No. 1 (the white fimbriation of the star). Official color: BCC Dictionary of Colour Standards, No. 210 (the red of the star). Also known as Union Jack Red.
