Color Transcends Form
This ties into the Great Wheel Metaphor which is about transcending. Krishna, of course, can do anything, can always make a miracle. But miracles are, by definition, exceptional, not general. In general, the rules of material nature apply rather than miracles, and miracles are extremely rare.
So just as color transcends the form, it doesn’t change the form. You can have Form, and no Color, but Form with Color transcends Form. Just as Life transcends Matter. You can have Matter without Life, but Matter with Life transcends Matter. The same as you study matter with physics, the study of life (as in biotic life, not Life as an abstraction) is biology. Biology transcends physics. Biology doesn’t transform (change) the laws of physics, but does go beyond them.
