: Thanks for the question. Wikipedia's articles are based on notability, meaning a topic needs to have sufficient coverage in reliable sources to justify inclusion as a standalone article.  The school color is deemed to have that coverage.  If other variants of the color also have sufficient coverage,  they might warrant their own article.  Another option is to include mention in this article about those other colors, but that would be determined by due weight i.e. how prevalent are the other colors covered in sources? Moreover, Wikipedia would base it off of independent sources to address the marketing concern that you raised. One way to think of it would be that the apple pie article should not be a coat rack to mention every apple pie baked in the world, even if it were true. Regards.—
