Colombians come in all shapes, sizes and colors, just like most people.
The majority are of mixed blood (Spanish and indiginous indians). This creates the mestizo look.
There does seem to be a high-percentage of attractive, young women from Colombia (as well as Venezuela, Brazil and Argentina).
Keep in mind this is not just genetics (although that plays a big part) but it's also cultural. They take pride in their appearance, they dress nice, they take care of their hair, face and bodies. They carry themselves well. They just look and smell nice.
They also have an "attitude" (this is true of MANY Colombians) that they are somehow superior to other Latin Americans. They think they speak a more pure form of Spanish and are smarter than the others.
One big plus is they have not grown up on American fast-food (yet). Also you will see many Colombianas in Costa Rica since economics forces many of them to seek employment where they can find it doing what they can to make money. Once word gets to them that there are gringos with money they will travel to find them. There is a reason there are so many marriage services featuring Colombian girls.
Thus you find attractive, intelligent (business-wise, can often speak some English and may have some post-high school education) Colombianas working at the Del Rey and in Jaco.

With over 41 million people, Colombia is the third-most populous country in Latin America, after Brazil and Mexico.
It also has the third largest Black/African-descent population in the western hemisphere after Brazil and the US.
The country has a diverse population that reflects its colourful history and the peoples that have populated here from ancient times to the present.
The historic amalgam of three main groups are the basics of Colombia's current demographics: indigenous Amerindians, European immigrants, and African slaves.
Many of the indigenous peoples were absorbed into the mestizo population, but the remaining 700,000 currently represent over 85 distinct cultures. The European immigrants were primarily Spanish colonists, but many other Europeans (Italian, German, French, Swiss and in smaller numbers Belgian, Lithuanian, Dutch, English and Croatian communities) immigrated during the Second World War and the Cold War. For example, former Bogota mayor Antanas Mockus is the son of Lithuanian immigrants.
The Africans were brought as slaves, mostly to the coastal lowlands, beginning early in the 16th century, and continuing into the 19th century. After abolition, a national ideology of mestizaje encouraged the mixing of the indigenous and Afro-Colombian communities into a single mestizo ethnic identity.
Other smaller immigrant populations include Asians and Middle Easterners, particularly Arabs, Chinese, and Japanese.
As of 2006, Colombia has about 3 million internally displaced persons, the highest number of any country in the western hemisphere, and second worldwide, after Sudan.
