Considering this, does clear have a color?
It's not only not a color, it's totally orthagonal to colors. Any color can be “clear”, meaning transparent or translucent, or opaque, meaning the opposite. Basically, “clear” is just a shortened way to refer to something that's transparent, or sometimes translucent.

Herein, is there a color that we Cannot see?
That's because, even though those colors exist, you've probably never seen them. Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously.
Will we ever see a new color?
Therefore, there are no new colors waiting to be discovered for us to perceive in the future. Of course, the above only applies to colors perceived through the perception of light through our visual system. We can also perceive colors through non-visual means such as hallucinations, dreams, and our imagination.
