Homogeneous
A homogeneous mixture is a solid, liquid or gaseous mixture that has the same amount of its components throughout a given sample. A homogeneous mixture can also be called a solution.
Heterogeneous mixtures
Heterogeneous mixtures are made of different substances that stay physically seperate. These mixtures always have more than one phase
Colloids
A colloid is a heterogenous substance made up of large or ultramicroscopic particles of one substance dispersed trough another substance, a great example of a colloid is gelatin. The video below will explain more to you
