I don't think you understand how the upgrading process works. When Simmental, Gelbvieh, etc. came across from Europe, people A.I'd their Black Angus cows to a continental bull. The resulting black heifer females were bred back to a continental bull resulting in abother black female. This was done for 3 generations to give you a purebred Simmental or Gelbvieh female. Bulls had to be one more generation to be considered pure. (Females are pure in Simmental at 7/8 and males at 15/16.) Black is the dominant color. They were upgraded more so in Canada from a Hereford base.
I am sure you know that the reason for this was the lack of any kind of performance in the belt buckle type cattle that existed at the time.
If the Angus and Hereford associations at the time would have been smart they would have opened their herdbooks at that time and allowed reverse upgrading. If they had, there would not have been any more than a few breeds in North America today.
