It consists of a round sun (without rays) of yellow-orange color with gradients and on top the names "Phineas" and "Ferb" stacked on top of the sun in red with brown edges in its own typeface (Ferbstastic) and below, a colored ellipse brown with the conjunction "and" (which could change its language depending on the territory) piercing it and slightly tilted to the right.
