referencing a field attribute or is dirty

[mainerain]

I want to take an action if a certain field is dirty. What would that look like?

or if Me.[field].BackColor = RGB(252, 230, 212) Then do this....

sub txtBox1_afterupdate()

 if Me.txtBox1.BackColor = RGB(252, 230, 212) Then
  msgbox "new data entered"
endif
end sub
