Hi, Jw74.
Cat was not always yellow. From the time of the formation of the company until late 1931, their products were painted a sorta 'battleship grey'. Then, from 7 December, 1931, Cat adopted the Highway Yellow that so many road authorities were using for visibility reasons as their standard color. From then on, for MANY years, you could have your new Cat delivered in any color you liked so long as it was Highway Yellow - - - - - - - UNLESS you wanted to pay extra for another paint job.
Just my 0.02.
olive drab for military too.
