the color of mercury is gray it has no color
greenish blue due to the chemical reaction from the c02 from the flame and the potasiam iode in the salt.
its a natural color
brickish color
A streak that has color or no color.

originially Dexcool which is orange color. if its been replaced with glycol, its green.
Coolant recommendations and cautions: The recommended mixture is 50/50 ethylene-glycol and low mineral content water. Never use pure antifreeze. Only Mopar Antifreeze Coolant, 5 Year/100,000 Mile Formula (glycol base coolant with corrosion inhibitors called HOAT) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water.
It is clear. If it is at room temperature, and 100% Ethylene glycol is clear.
propylene gylcol is Green in colour and is used in a number of applications as it is much less toxic than blue coolant. Although it requires a more specialist tester than standard coolant and cost from £8 upwards

IT doesn't matter what color coolant you use, it matters by what mixture you use it. Some ethylene glycol coolants are yellow, like Pres-tone for example, others are green. Follow the direction's on the jug for correct mixtures as some are premixed and others are not. If you already have coolant in your truck, and your wondering why it's one color or another, don't worry about the color, use a $1.00 hydrometer from Pep Boys, Auto Zone or anywhere, and check the mixture of the coolant to make sure your vehicles water coolant mixture will not freeze at a certain temperature, like 10 below or 20 below the freezing mark or what ever the manufacturer states it should be. It was built with green.
"Engine coolant" can mean water or anti-freeze, whichever circulates through the engine to draw heat from the block, through the radiator where it is cooled by the fan and then recirculated. Anti-freeze (ethylene glycol, which is sweet-tasting and often fatally ingested by pets and children) is preferred over water because it doesn't promote rust and is a more effective coolant. There are numerous types of coolant/antifreeze on the market and NO they are not all the same. Though many contain ethylene or proplyene glycol the corrosion and rust inhibitors vary greatly from type to type. For example Dexcool (orange) is an HOAT coolant and should not be used in ford motor vehicles. You should follow the manufacturers instructions and use the correct coolant. No matter what some companies say i.e. prestone, there is no such thing as "any make, any model, any color" coolant.
Most new coolant is tinted red or green. If you have a different color than that look into it a little further. You may have oil in you coolant causing it to be a brown color.
Chrysler uses their own special formula of coolant, which is actually a hybrid, that is cross between ethylene glycol based coolant(green) and the organic acid technology (orange) coolant, comonly known by the brand name Dex-cool. It is identifiable by it's distinct red color. Some may cofuse this with the orange Dex-cool, but it is not the same thing, and should not be mixed. In other words Chrysler coolant is unique, and you should only use coolant specifically made for Chrysler vehicles.
Open your radiator cap and see what color the coolant is and replace it with the same color coolant, it doesn't matter what brand it is.
dex-cool coolant---it is orange in color.
