My tractor is blue under the mud (I won't clean it until it stops raining). My rotary cutter is a Rhino, so I guess it was red, but the color was already pretty faded when I got it new, from sitting outside at the dealer - they buy them once a year. I can't remember what color my box blade is - yellow or orange, I think. I never paid much attention. When I bought my landscape rake at TSC on sale, I did make them take the second one in the row because the first one was pretty weathered - but first, I tried to get a reduced price on the weathered one. I painted my home-made root rake black to match my bucket, but I started using it before the paint hardened up, and I'm not sure what color it is now, mostly primer -- but that's OK, because most of the paint has been worn off my bucket, too, down to the primer, which is kinda reddish orange.
If all that sounds sort of apathtic, I'm like the other fellow above - everything is greased, tight and ready to operate. I do wash the bird poop off it when it occurs.
As for looking good, the way I usually look, and the clothes I wear when working, I'd look silly on a Martha Stewart coordinated tractor.
