Perhaps related, it is intriguing that only a “shape” can be “black”. It seems challenging to imagine a “light” as “black” outside of the convention of using the term “black light” to describe a wholly different phenomena.
At which point can a surface be distinguished from a light? This would seem to critically hinge upon the idea of a local increment in the field.
Extending to colours, an energy *increment* would appear to be a prerequisite for something to be bound as a “light”.

@troy_s A ganzfeld appears white. Also a darkroom can be described as black in terms of its volume. Ultimately none of these terms are well defined without a model. That’s the central problem of psychology; namely, the habit of defining perception in self referential terms. You just end up in an infinite regress.
