A colloid is actually a heterogeneous mixture. HETEROGENEOUS MIXTURE- Heterogeneous mixture means the mixture in which the particles are not uniformly mixed with each other.

So according to me colloid mixture appears to be a homogeneous mixture but actually it is a heterogeneous mixture.

What is the difference between colloid solution to colloid mixture?
Well they are the same thing because a solution is a type of mixture. If there had to be a difference a colloid solution is when particles are mixed as a colloid in water but a colloid mixture could be anything: a gas colloid, a liquid colloid or a solid colloid. Or any of those three mixed together! It is complicated but basically the difference is that one is particles spread thought mixture and one isn't. Hope it helps :)
