What medium/material (markers, colored pencils, acrylic) makes color the most vibrant?

Hello, I am looking for something that makes color the most vibrant, strong, pure. I was curious on which medium or material makes color the most it can be? Like do markers make red the most red? Or acrylic? Or oil pastels? Was just curious and thinking about it, would love your opinions. Other variables could be the most opaque or stand out the most. Am working on something related to color theory and want to represent each color with the best version of itself possible.
