If only i can delete my previous post.. hmm never mind.
The code below are TESTED and working like i (or may be you) wanted it to..

Private Sub cboColor_AfterUpdate()
Dim iResponse As Integer

If Me.cboColor = "Yes" Then
'--Enabled all check box
iEnabled
Else
If iCheck = False Then
iResponse = MsgBox("YourMessange", vbYesNo, "Title")

If iResponse = vbYes Then
'--change value to False
chgFalse
'--disable all check box
iDisabled
Else
Exit Sub
End If
Else
'--All check box = True
iDisabled
End If
End If
End Sub

Private Function iCheck() As Boolean
Dim ctl As Control
iCheck = True

For Each ctl In Me.Controls
If ctl.ControlType = acCheckBox Then
If ctl.Tag = "Col" Then
If ctl.Value = True Then
iCheck = False
Exit Function
End If
End If
End If
Next
End Function

Private Sub iDisabled()
Dim ctl As Control
For Each ctl In Me.Controls
If ctl.ControlType = acCheckBox Then
If ctl.ControlType = acCheckBox Then
If ctl.Tag = "Col" Then ctl.Enabled = False
End If
End If
Next
End Sub

Private Sub iEnabled()
Dim ctl As Control
For Each ctl In Me.Controls
If ctl.ControlType = acCheckBox Then
If ctl.Tag = "Col" Then
ctl.Enabled = True
End If
End If
Next
End Sub

Private Sub chgFalse()
Dim ctl As Control
For Each ctl In Me.Controls
If ctl.ControlType = acCheckBox Then
If ctl.Tag = "col" Then
If ctl.Value = True Then ctl.Value = False
End If
End If
Next
End Sub

Yes I think you do need another For Next loop if you are going to warn the
user *only* if any of the CheckBoxes are checked not least because your
[quoted text clipped - 30 lines]
through the controls automatically it should mean the user gets one
prompt and not, e.g., 10.
