What code should I write in Python?

Given primary colors $($Red$,$ Blue, and Yellow$)$ create a sequence of if$,$ elif, and else statements that will "calculate" two colors mixing.

Your code must:

$$ Take user input for color$1$ and color$2.$

$$ Account for all possible color outcomes given those two inputs: $*$Notice some color combos are similar. Remember the user can input colors in different orders!

o Red $+$ Red $=$ Red

o Red $+$ Blue $=$ Purple

o Red $+$ Yellow $=$ Orange

o Blue $+$ Blue $=$ Blue

o Blue $+$ Red $=$ Purple

o Blue $+$ Yellow $=$ Green

o Yellow $+$ Yellow $=$ Yellow

o Yellow $+$ Red $=$ Orange

o Yellow $+$ Blue $=$ Green

$$ You must also account for user input errors or invalid inputs, since Python is case$-$sensitive you have to be prepared to handle all variations of color inputs $($e$.$g$.$ red, Red, RED, rEd$).$ Also, be aware a user could input absolutely anything so even though you expect only the three primary colors you also have to account for the user entering something like $$Shoe$.$ What are you going to do in these cases?

Example of what an output could be:Choose a primary color $($Red$,$ Blue, or Yellow$)$ Yellow

Choose a second primary color $($Red$,$ Blue, or Yellow$)$ Blue

Yellow and Blue combined create green.
