Copying headers of red text to another range - excel

Question

Goal: Have the column header of any text in red be represented in column F of the same row as the text.
Problem: Code currently references active row, and for some reason copies F2 (which is written in red). I know the code currently would be attempting to copy/paste over a cell a few times, and I'll work that out later.
Sub CopyRed()
Dim rng As Range
Dim row As Range
Dim cell As Range
Set rng = Range("G3:BF900")
For Each row In rng.Rows
For Each cell In row.Cells
If cell.Font.ColorIndex = 3 Then
Cells(2, ActiveCell.Column).Copy
Range("F" & (ActiveCell.row)).Select
ActiveSheet.Paste
End If
Next cell
Next row
End Sub

Answer 1

Not sure if I follow your logic. Your problem is that you reference active cell but you are not defining it or changing it other than through the pasting. I think you mean to reference cell (?)
Sub CopyRed()
Dim rng As Range
Dim row As Range
Dim cell As Range
Set rng = Range("G3:BF900")
For Each row In rng.Rows
For Each cell In row.Cells
If cell.Font.ColorIndex = 3 Then
Cells(2, cell.Column).Copy Range("F" & cell.row)
End If
Next cell
Next row
End Sub

Answer 2

You are never changing the active cell, so the copy command is always called on row 2 of the active cell, which much be in the F column. I changed the code below to fix the issue.
Sub CopyRed()
Dim rng As Range
Dim row As Range
Dim cell As Range
Dim ws As Worksheet
Set ws = ThisWorkbook.ActiveSheet ' this should be improved to point at the correct worksheet by name
Set rng = ws.Range("G3:BF900")
For Each row In rng.Rows
For Each cell In row.Cells
If cell.Font.ColorIndex = 3 Then
cell.Copy
ws.Range("F" & (cell.row)).PasteSpecial
End If
Next cell
Next row
End Sub
