Not exactly. Hinduism is dull red ochre (Buddhist monks wear clother of a darker/brighter hue). We term the color as 'Bhagwa'... and Hinduism orange ..
Even diamonds have colors - Mahayana, Vajrayana, Theravada, Pure Land. There were many others in history.Buddhism is the Vajra or diamond religion. It has no color --
Is that not the grave?"... All will I gather beneath the one-colored covering of the dust and efface all these diverse colors ... "
I that not black, or rather darkness, the absence of all colour?"... save them that choose My own, and that is purging from every color." - Baha'u'llah
Supernal Triad, Deity above all essence, knowledge and goodness; Guide of Christians to Divine Wisdom; direct our path to the ultimate summit of your mystical knowledge, most incomprehensible, most luminous and most exalted, where the pure, absolute and immutable mysteries of theology are veiled in the dazzling obscurity of the secret Silence, outshining all brilliance with the intensity of their Darkness, and surcharging our blinded intellects with the utterly impalpable and invisible fairness of glories surpassing all beauty.
