Are Ferrari's Still Hyper-sensitive to Colour?

Dear Comrades,

Red is undoubtedly still the number one colour for Ferrari's. But does a particular colour degrade the value and if so by what percentage? For example, would yellow be the same price as a red car? If not, by how much would it be devalued? Indeed, is black still desirable or would this shade make any given car less valuable then the ubiquitous red?

With kind regards,
