Yes, but I think we are talking about two different lists of colors.: one for commercial vehicles and one for passenger cars. It makes sense that if Ford opened up the range of available colors for trucks, he did the same for passenger cars. A customer is a customer. and by mid-1931, they were becoming scarce due to the continuing effects of the Great Depression. I gotta' believe even then there were more potential passenger car buyers than for commercial vehicles. So, why not make more options available to the larger customer base?
I didn't imagine the list of colors for passenger cars appearing in an old "Restorer" issue. But I am also not inclined to wade through hundreds of back issues just to find this article to prove my point. Let's just leave it that the list the OP posted applies to commercial vehicles only. Good information. If I ever stumble across the article I am referring to, I'll post the information.

I am only aware of two different Letters sent by the Dearborn Branch. One was sent on June 4th and the next one (-dated June 5th) was some clarification of the June 4th letter. The Indianapolis Branch also sent similar letters. Likely, a similar letter originated from each of the Branches (i.e.: Factories). This June 5th Letter basically references the June 4th Letter and explains how the program will be implemented.
I think this is where your thought might have come from regarding offering these special colors to regular customers. Back some 10-15 years ago, I was trying to make an argument that this June 5th Letter could apply to a non-business concern because of some verbiage. In Paragraph 2 of that Letter, it basically said '
When passenger cars are purchased for commercial concerns for business use, the passenger cars can be painted any of the colors... (-on the attached list.) It gave pricing for Fleet purchases of less than 10 units at N/C, and a price for 10 or more units at N/C.
So, my argument was Ford was willing to cater to a business concern for under 10 units. My argument was they did not specify a number under 10 units, ...and 1 unit was a number under 10. It also did not specify what a business concern was, and so a travelling salesman, or a Dentist or Dr. making house calls as a part of their occupation could effectively be considered a Business. At that time, the MARC JSC was not willing to offer a variance for a hypothetical scenario unless I could provide documentation by a Ford Branch or Agency showing this passenger vehicle was ordered as a business concern and listing those colors. Likely, offering special colors to a regular consumer never happened, but in today's world of stretching the truth to make someone believe your pitch, I guess it could be believable by some.
Oh, and my belief of Ford's poor sales in 1931 wasn't really because of a failing economy. After all, while the unemployment rate was approaching 25%, it was only affecting around 1 in 4 people. My belief was people were still buying cars, -just not Mr. Ford's cars. Chevrolet was outselling Ford about 3 to 1 in 1931. I believe Mr. Ford knew deep-down that his product was tired so in 1932 by offering the V8 and the 50hp 4 cylinder, he narrowed the sales gap where Chevrolet was only outselling him 3 cars for every 2 he sold, but at that point the damage was done. It would be years after the Depression before Ford would be close to Chevrolet in sales.
