Hi @LYNCHJL ,
Based on the needs that you mentioned, I agree with @eka24 and @WarrenBelz 's thought almost. You could take a try with them to achieve your needs.
As an another solution, I think the IsMatch function could achieve your needs. Please consider set the Fill property of the Text Input Box to following:

If(
IsMatch(TextInputBox.Text, "Type Specific Word Here", MatchOptions.Contains), // Replace TextInputBox with actual control name in your Edit form
Color.Red , // changed bg color
RGBA(255, 255, 255, 1) // defualt background color
)
Please consider take a try with above solution, then check if the issue is solved.
Best regards,
