Is it a painting thing possibly? Like where the black plastic being painted makes the suit look more like pleather than spandex?

I could be wrong, but I assume what he meant was the fact that the Dekarangers have the one elbow molded in black, but all their other joints are molded in their respective color. The Gokaiger's also have elbows that are their respective color, and knees that are black.

So then they should just mold them in the main colors of the arm. It didn't stop them from doing the red on BoukenRed's knees.

Actually, the suits in Go-Busters are leather. :lol

Also, Bandai is smart enough to not put paint on joints.

Yeah. I'd say mold them in silver rather than black.

SO glad I jumped on the Itasha preorder. That thing is pure glory.
