Is it true that colloidal solutions have charged particles as solute particles?or, is it a suspension?Im confused....

To use the terms correctly you cannot use both colloid and solution for the same mixture. These terms mean different things. A solution is a homogeneous mixture while a colloid is a heterogeneous mixture.
No, a colloid does not necessarily have charged solute particles. By definition, a colloid is a mixture with solute particles which are held in the solvent by some type of attractive forces - either charged (dipole-dipole) or uncharged (dispersion) forces. A colloid will disburse a beam of light if you try to shine it through the colloid. In other words the colloid looks cloudy. This is due to the particles which are held in the mixture by the solvent. Examples of a colloid are milk, shampoo, hand lotion, dirty dish water/dish detergent mixture.
A suspension is a heterogeneous mixture with particles large enough to settle out of the solution. Examples are paint, chocolate and milk, orange juice and pulp.

The term colloid means ONLY that the solute has a high molecular weight.
As water is a polar liquid , colloids which are soluble in water must bear charges Polyanions like DNA, polyamines

YA THEY VE CHARGED PARTICLES USUALLY A PART BECOMES CHARGED DUE TO SURROUNDING BY CHARGED PARTICLES FORMATION OF MICELLES OCCURS AS IN CASE OF SOAP BUBBLES

Add some blue ink to milk... that will do the trick
