This image is by Soorya Kaur and taken at the Ranch in Espanola, NM, USA in February, 1988.  It was published in her book, YogiJi the Light of Our Souls.  Here’s what she wrote about it:

YogiJi wore white – a long simple robe was his usual attire.  He said white contained within it all the colors of the spectrum, it symbolized purity; and for the white clad 3HO family, it linked them together, and stood for their united consciousness.

During the summer camps however, he loved wearing his rainbow hued phulkari robes, hand-embroidered by the women of his beloved Punjab in India.
