Double Claro
While oftentimes greenish to slightly greenish, this wrapper can also be of a yellow shade. It is achieved through a heat-assisted, fast drying process retaining the chlorophyll content of wrapper leaves. These wrappers have a very mild flavor. At one time these were very popular cigars, but interest had waned. There has again been an increase in the offering of these cigars recently.


Claro
This is a "shade-grown" tobacco, which typically has a light, tan color. Tobacco plants that yield these wrappers are usually grown under shade tents and the leaves are picked before they mature. They are then quickly air-dryed. Claro wrappers are typically mild (neutral) flavor.


Colorado Claro
Typically called "Natural", this wrapper often is a light brown in color and is most often sun-grown.


Colorado
Colorado wrappers have a range from medium-brown to brownish-red shade. These wrappers typically are shade-grown and characterized by a rich, sweet and fairly strong flavor. Colorado wrapped also cigars tend to have a subtle aroma.


Colorado Maduro
The color of this wrapper is somewhere between Colorado and Maduro, and is (as you point out) most notable in the Cameroon leaf from Africa. These wrappers have a distinctive sweet, rich and pleasantly spicy taste.


Maduro
The word Maduro means "ripe" in Spanish. It references a longer wrapper leave fermentation process, or most often are cooked in a pressure chamber to produce their distinctive wrapper color. These wrapper colors can vary from a dark reddish-brown to a very dark brown and are primarily grown in Connecticut, Mexico, Nicaragua and Brazil. Cigars wrapped in a Maduro wrapper can vary in taste from mild/mellow to sweet and typically produce strong, earthy flavors with a mild aroma.

Oscuro
This wrapper is sometimes also called "black" or "negro" and is typically darker than Maduro. Oscuro is produced by leaving the wrapper leaves on the tobacco plant for a longer period of time before harvest. Only those leaves which have had the most sun (the top part of the tobacco plant) are used and they are fermented for a longer period of time to produce a dark, rich, oily "toothy" wrapper. Not unlike Maduro, cigars wrapped in Oscuro are sweet, strong and earthy with a mild aroma.
