While everyone’s comments have merit the true fact here is you CAN NOT patent a color. Simply by removing the name Macintosh removes all liability because the average consumer can no longer be confused between the two brands of Hifi Rose and Macintosh. I am very certain Hifi Rose received a demand letter requesting the name be removed due to the potential for product confusion no matter how small a chance that maybe. Macintosh is not so amateur that they would demand a color be removed from a menu of choices. The “Macintosh,” blue style meters prevail on many devices they are most certainly NOT referred to as Macintosh blue unless, well if they are on a Macintosh unit.
There is no reason these VU meters can’t be returned as long as Macintosh is nowhere to be found within the ROSE software / interface, so the reason to holding them back is confounding at best but such is life.
