Early Reeds were black. IDK what color the mid-century ones were.

From what I've seen, I think the Reed works went to a medium grey colour sometime after the war, possibly late '40's early '50's.
As a generality, with, doubtless quite a few exceptions, it would appear that most of the 'old-line' vise makers used the common 'industrial black' medium-gloss paint for their 'industrial' lines, and various 'more attractive' colours for their less-expensive lines meant for the motor trade and home-shop applications.
The 'home hobby shop' market, in vises, was a very competitive one, in which 'styling' and colour were aggressively pursued, to attract such buyers as might prefer a 'modern-looking' vise......much as car makers of the 'art deco age' were doing.
At a guess......and this is only a guess......the vise makers didn't see any need to compete on 'colour' or 'sales attractiveness' of their industrial lines, on the theory that the purchasers simply didn't care about the colour of their vises, or would re-paint them in 'company standard' colours, whatever such might be.
There were exceptions, to be sure.......I've seen Prentiss vises with nicely done nickel plating, or filled/rubbed castings, in a 'brick red' or 'deep wine red' with 'straw' line-striping, and, tho I've never seen one myself, the Parker works advertised their 'white vises' as a 'sales ploy'.
(I can imagine a new fad, of 'image-conscious' vise owners doing high-quality refinish on their old vises, with filled/rubbed castings, and rubbed paint finishes, with line striping........or, imagine replicating one of the 'special order' nickel-plated Prentiss vises, with highly finished castings......for that matter, imagine a new fad for polishing-out and nickel-plating the Wilton vises....they would look 'dramatically fancy' to be sure)
I'd think it quite plausible, but don't know, first-hand, that some supply houses might have specified a 'house colour' when ordering stock quantities of vises from a manufacturer....again, a bit of 'sales image'.
(added on edit.......this certainly was done, in some instances, such as the Snap-On Co. offering Wilton vises painted 'Snap-On red', and with a 'Snap-On' logo sticker.......and one will sometimes see larger vises of other makers which appear to have been originally painted in red, as well, as that colour became common in equipment for the motor trade.)
