Color is not that much of a deal..... Different manufacturers have different color coolants but the blend is really the more significant thing.... I would recommend that you check your owners manual and use what the Toyota engineers specified for your truck....
If you are a new owner and there is any question at all on the service history, you might consider replacing all your major fluids just to be sure.... Cheap insurance if you plan on keeping your truck for a long while.... Radiator is the easiest and depending on the mileage you might also want to include transmission, differentials and brake fluids....
