Color mix
Working at a design studio is exciting. Mixing colors together can produce other interesting colors. The wonderful thing is that any color can be produced as a result of mixing red, green, and blue colors together.
Yet, doing that experiment every time is time-consuming and it would be great to have an automated process that would print the resulting color after mixing different colors together.

Our task is to automate part of that process and print the resulting color after mixing any of the red, green, and blue colors (The image on the right can be used as a reference).

The program gets as an input 2 colors that the designer wants to mix. Sometimes they do typos or input invalid colors - in that case, the program should print Invalid color. Otherwise, the program should print the result of the mix.
