Colloids are particles of a certain size...around a micron to a fraction of a micron in diameter.
The key characteristic is mass/size...they are insoluble but form a suspension when added to a solvent...
That is to say they tend not to precipitate or form a deposit...they float...
gravitational forces are balanced by the physical properties of the solvent...
think of upthrust.
