The color of the gages on a 1951 or 1952 Kaiser are the same. Check out the exploded view of the instrument cluster in the 1951 Kaiser and Frazer Factory Shop Manual . It's illustration 444 on page 323. King-Seelet made generic gages that, as this illustration shows, have no lettering or numbers on them. the actual markings are on the dial plate Further the 1951 Kaiser Illustrated parts book shoes a similar illustration on page 130 as firugre 19-2. The wording (Fuel, etc) and status (full, temperture in degrees F., etc) is on the dial. There were no choices in color but King-Seeley, the vendor for the gages made the display in different colors as the same unit was used on other makes of car or light truck. They were color coded for the different makes. As the parts book shows in Section 19, there was only 1 combination when it came to gage color.
Hope this clears things up.
