I don’t believe so. Because you’re always drawing things closer together. So with those extreme colors, you can’t find anything on the other side of it to draw your resultant mix to. Instead you can only overwhelm the mix to duplicate the original color some.
The same is technically true for Black, White, and all the really bright pure colors on the edge of things
If you imagine the colors as points in a 3d shape, with the luminous colors all at the top, (white is actually like a dip in the top, because it’s a tad grey), black at the bottom and those colors around the edge, it becomes kind of a ravioli shape. You have to be able to draw a line between two colors to get a mix color, and since all the edge colors have nothing beyond them to throw in to the mixer, they are the end of their respective lines.
