From left: National Flag of France (CS); National Flag of Ecuador (fotw); National Flag of the Republic of Congo (CS) Please note that the definition of tricolour (as given herein) is restricted to flags of three colours disposed in three stripes, and that flags that do not fall into this category are defined elsewhere. Please note also, that the Editors have drawn a distinction between flags with three stripes and three colours, and those consisting of three stripes but only two colours, with the definitions for tricolour and triband having been carefully drawn up using all available sources.
A tricolour is a flag or banner having three colours, usually in approximately equal size (horizontally or vertically) and lacking additional symbols. One of the first tricolours and the oldest tricolour still in use today is the flag of the Netherlands; one of the first vertical tricolours is the Tricolour of France.
