How can I make my script a bit less repetitive?

Hello, so I'm tired of adding a bunch of if/elseif statements to my scripts where I have to check if the thing that got selected in a table matches to what I inputted, and I just think theres a better, and neater way to do this stuff.

Here's an example:

local foods = {"Apple", "Banana", "Grapes", "Carrot"}

function getColour(food)
   if food == foods[1] then --Beyond here is a bit repetitive, how can I change this?
      print("Red")
   elseif food == foods[2] then
      print("Yellow")
   elseif food == foods[3] then
      print("Purple")
   elseif food == foods[4] then
      print("Orange")
   end
end

getColour("Banana")
