Changing text color and textbox color on Access Report

Hi,

I'm trying to change the text color and textbox color whenever a user
input from another form says "BLACK" to "Color Preference". By
default, the textbook's background color is white and text's color is
black, but when the user input "BLACK" to the color preference, I
would like to change the color of the textbox on the report to black,
and therefore the text color to white (otherwise it can't be seen).

How do I do that? Is there a VBA code that does this? I have to link
the user's answer from another form to the textbox that's in the
report.

Thanks a lot!
