Six Forgotten Warriors Chapter 5: The Price of Heroism - S5-E6
Plot hole: This series is in the same continuity as the other Marvel animated series from around the same time - X-Men, The Incredible Hulk, Iron Man, and Fantastic Four - by virtue of each aforementioned show crossing over with at least one of the others. This episode, which originally aired on October 17, 1997, establishes that Captain America had spent the last 50 years locked in another dimension with Red Skull, and the episode ends with he and Red Skull once again becoming trapped in the aforementioned dimension. However, the final episode of Fantastic Four, entitled "Doomsday," which originally aired on February 24, 1996, features a cameo by Captain America in the present day, attempting to stop a rampaging Dr. Doom.

Continuity mistake: When Captain America and Red Skull are grappling near the vortex, their fingers are interlocked. When the shot changes, their hands are pushing against each other's torsos.

Other mistake: Two scenes in this episode are shown out of order. First we see Captain America and Spider-Man lying on the ground near the dimensional vortex at the mercy of Chameleon and the Red Skull, with Cap flicking a rock across the room to distract Chameleon so that he and Spider-Man can re-engage them in battle. Shortly after, we see Spidey and Cap arriving at the dimensional vortex to configure it to defeat Electro, with Chameleon and Red Skull attacking them once Spidey has finished with the vortex, revealing they had been lying in wait knowing full well someone would figure out that the vortex was the key to stopping Electro.

Continuity mistake: When Captain America is giving Spider-Man moral support after Mary Jane's accident on the roof, the red glove on his right hand briefly turns blue when he puts his hand on Spider-Man's shoulder.

Other mistake: When Spider-Man and Silver Sable are chasing the Red Skull and Kragov, they are able to deduce which direction they are going by identifying their footprints. However, Spidey and Silver Sable themselves don't leave footprints when walking over the same spot.
Answer: I believe it was just a way to try and show the suit is "oily" or reflective. It also helps define the character's features since otherwise, he'd just be a flat black color. It's similar to how the black suit Spidey had blue outlines. (I don't know why they chose a pink/red color... maybe because red is associated with power/fire/war, so it's a more "evil" color?)
