Sorry if my suggestion was interpreted as anything other than tongue very firmly in cheek!
About the site I linked to, they are professional Studebaker restoration people, and own their own Studebakers as well. The site does give some of the background on some of their posted formulations and how they are to be adjusted, for metallic effects as an example, and how they matched colours, using what (sometimes multiple) sources.
Its often tricky even with white. The particular off-white wheel colour used up to 63, (and how that differs from 64 and the 65-66 wheel white), which is even different from the white used on the hubcaps on my 63 Wagonaire, which differs again from the Ermine white which is the original colour of my car, and different again from Astra White of a 64 I'm looking at buying. So, looking at my car from the side (once it is repainted), the body/wheel/whitewall/hubcap would all be different shades of white! Dizzying!
Here is car on Ebay that is more or less exactly like MY car should be, inside and out, except that it has the Deluxe hubcaps without the white paint on them. Needless to say, I grabbed lots of the pictures as aides memoires.

Ray and Lin wanted to avoid some of the pitfalls as pointed out here about an owner having spent a lot of money and not getting the right match...and not, therefore, in a frame of mind to accept outside opinions.
The few Kaisers and Studebakers in my home town when I was growing up happened to be 'interesting' colours, and I studied them closely. ie, the difference between 53 Stardust and 54 Palm Beach Ivories (I much prefer Stardust), Jade Tint, that beautiful 51 Frazer mid green metallic (Tropical?), Copperdust, and the Maroon Velvet of the 53 Dragons, and of course, Studebaker Black Cherry.
