Maybe something like this... you'll need to deal with the things you're not telling us.
Code:
Sub CopyRedValues()
Dim cel As Range
Dim writerow As Long
writerow = 2
For Each cel In Sheets("source sheet name").UsedRange
If cel.Interior.Color = vbRed Then
cel.Copy
destinationworkbook.Sheets("ANOTHER").Range("A" & writerow).PasteSpecial xlValues
writerow = writerow + 1
End If
Next cel
Application.ScreenUpdating = True
End Sub
