Why did Kashiram give Maharaj a green kafni if he knew Maharaj only wore white?

The source text from Chapter 0 notes that Kashiram did stitch and give Maharaj a green kafni and cap. It also mentions that Maharaj usually wore a white kafni. However, the text does not state that Maharaj *only* wore white, nor does it explain Kashiram's motive for choosing the color green. It is possible Kashiram's gift was an act of devotion, and the text does not suggest he was knowingly going against a strict preference of Maharaj. The passage simply presents the facts of the gift and Maharaj's usual attire without drawing a connection or conflict between them.
