This is a discussion on *Conversion to and from the Munsell color model* within the **C++ Programming** forums, part of the General Programming Boards category; I'm looking for a clear description of what equations need to be applied, but haven't had any luck with Google ...

## Conversion to and from the Munsell color model

I'm looking for a clear description of what equations need to be applied, but haven't had any luck with Google and Wikipedia. Anyone know of a good source for this? Thanks.

Code:bool fun(bool value) { return std::pow(std::exp(1), std::complex<float>(0, 1) * std::complex<float>(std::atan(1)*(1 << (value + 2)))) .real() > 0; }

it looks like it's essentially HSL done with subtractive RYB color instead of additive RGB

there's a javascript RYB to RGB converter in the source of this page:

wiki has formulae for converting to and from HSL/RGB

Well, just keep in mind that the model isn't entirely mathematical; rather, it's based on observed perceptions of color, and so it requires complex calculations that generally require actual tables of data, which are typically fed into matrices to calculate the conversion. But thanks for the links, I will look into it.

Code:bool fun(bool value) { return std::pow(std::exp(1), std::complex<float>(0, 1) * std::complex<float>(std::atan(1)*(1 << (value + 2)))) .real() > 0; }
