Making column titles appear in assigned row

Hello -

Please see the attached document for an example. You will notice columns B-H are titled separately. Cell A2 lists all of the columns titles with an "X" value, as does A3 and A4. There was no formula that I applied, I just marked it off manually. What formula can I use to make excel list all of the appropriate column titles, or colors, in A5 and A6?

Hope this is clear. As always thank you for your help.
