I'm curious if anyone knows of a set of color filters that correspond to the standard Macbeth chart colors.

In theory I should be able to use a filter with a transmission spectra curve identical to the reflection curve of a Macbeth chip, point at a flat white target like a Spectralon target, and read the same rgb histograms that I would from the chip.

Just an idea I'd like to try out.

    In theory I should be able to use a filter with a transmission spectra curve identical to the reflection curve of a Macbeth chip... The difference between theory and practice is that in theory, there is no difference between theory and practice. Meaning, transmission spectra and reflection spectra will never be the same.

    What photographic problem are you trying to solve? Why do you think this would be a solution to that problem?

Now appearing by special request, a comment in the answer box !

"Is this a dagger ( filter ) which I see before me, This handle toward my hand? Come, let me clutch thee.

I have thee not, and yet I see thee still.

Art thou not, fatal vision, sensible To feeling as to sight? Or art thou but A dagger ( filter ) of the mind, a false creation, Proceeding from the heat-oppressèd brain?"

    @Hueco "To be ( a color chart ), or not to be ( a color chart ): that is the question. - or is that the question? "What light through yonder window breaks" and how should i set my white balance? somebody stop me. Please.

Not possible to choose filters unless one knows the spectrum of the illuminant
