While making a mixture of cobalt violet light and Old Holland ochre on John's palette, Tony described the resulting color as something one might feed to an "orphaned baby creature" with an eyedropper. The creature he had in mind was a koala, which, he explained, one would probably have to feed something really easy to stomach, like watered down grape jelly (think of cobalt violet light and you might see some connection here). And what about the ochre? "That's for fiber." Of course.
And so "Koala juice" has been added to the Ryder Studio color vocabulary.
