Starch turns a blue-black color when treated with a few drops of iodine solution. This color change occurs due to the formation of a complex between the starch molecules and the iodine ions.

A potassium chloride (KCl) solution is colorless.
Aluminium carbonate solution is usually colorless.
If pure, colorless.
Silver sulfate solution typically appears colorless.
No colour
Generally the appearance is that of a dusty substance, the colour changes depending on the acidity of the solution when it was in its liquid form and if an indicator was used, usually it is white and dusty. :)
An indicator is a substance that changes colour in the presence of another substance. Let say inside the beaker are substances of both glucose and starch. The glucose and starch are of same colour. By injecting the lugol's solution into the beaker, the lugol's solution changes colour in the area of where starch is, while no colour changes in the presence of glucose. Thus, by using the Lugol's solution which only acts as indicator for starch and not glucose, we could tell part which area floats around with glucose and starch substances. Lugol's solution works as an indicator because it will stain starches due to iodine's interaction with the coil structure of the polysaccharide.

The universe as a whole does not have a specific colour. However, in a science experiment, when an antacid solution is added to a universal indicator, it may change colour based on the pH level of the solution. This change in colour signifies the acidity or alkalinity of the solution.
A potassium chloride (KCl) solution is colorless.
