This is one of the problems with having a standard color variety that references another breed. Other breeds sometimes will convince the APA and ABA to change their standard descriptions. I know this happened with Brown Red Moderns where the color used to be orange and then was changed to lemon. I think this was done to be more consistent with the description for lemon blue. The problem was that it is very difficult to breed brown reds with a lemon top color even from lemon blues. So then they petitioned to change back to the orange top color. By default, any breed that referenced the modern game brown color also changed and had the same problems.
Something to keep in mind as we proceed with adjusting the color description for Silver.
