Using a function makes it easier to call from different places. isOdd
is self-documenting, where inline code might not be. If error-
detection code (checking that the value is a number, etc.) is
necessary, putting it into a function once is better than adding it
everywhere.
That said, there is overhead associated with calling a function, and
this _is_ a very simple function. If it's being written for just this
one application, then doing it inline is certainly an option.

get "blue"
if x mod 2 = 0 then get "red"
put it into colorChoice

Note that for these functions, 2.5 is neither odd nor even, and non-
numbers cause an error. To be safe you would use:
function isOdd x
if x is a number and x mod 2 is 1 then return true else return
false
end isOdd
function isEven x
if x is a number and x mod 2 is 0 then return true else return
false
end isEven

How does one determine if a number is odd or even?
For example I would like to do something like this:
If the lineNumber of line x of fld "List" is odd then set the
textColor to red.
Suggestions are appreciated.
