But he added a spin of his own to the designs. 

Eight prototypes for the wall are under construction near San Diego, and the president has said himself that "they're looking really good."

Colbert's descriptions, however, were bleaker. 

"First up, we have the Venetian," the "Late Show" host said in his Friday night monologue, holding up a photo of a segment of wall. "This delightful open concept for a closed border."

"See-through means that immigrants can see a better life, but they can't touch it," he quipped. 

Colbert then turned his attention to another segment of wall, which he dubbed the "Continental" — a towering slab of concrete topped with razor-sharp spikes. 

"Fun feature: It keeps people out, but also makes the country seem like a prison from the inside," he said. "It's a twofer."

Colbert's final pitch focused on what he called the "Monolith."

"Thirty feet of pure reinforced concrete, this model is the apotheosis of brutalist architecture paired with the timeless tradition of fearing brown people," he said. "Enjoy."

Trump has vowed to build a massive wall along the southern border that he says Mexico will pay for. Days after taking office, he signed an executive order authorizing the construction of the barrier. 

But the president has also faced pushback from Democrats and some Republicans in Congress, who have railed against the proposal as ineffective and costly. What's more, Mexican President Enrique Peña Nieto has insisted that his country will not pay for the wall.
