Yes chromatography is a feasible mthod to seperate the bucket of mixed paint because it is a broad of range of physical methods used to seperate and analyze complex mixtures.Mixture of various components enters a chromatography process of different components are flushed through the system at different rates of migration as the mixtures moves over adsorptive materials provide seperation.In fact, chromatography can purify basically any soluble or volatile substance if the right adsorbent material, carrier fluid, and operating conditions are employed. Second, chromatography can be used to separate delicate products since the conditions under which it is performed are not typically severe. For these reasons, chromatography is quite well suited to a variety of uses in the field of biotechnology, such as separating mixtures of proteins.

Advantages
Less expensive
Used in both analytical and preparative application
Quick to perform and easy to master
Disadvantages
Cant be applied in large quantities
Does not allow seperation of complex mixture
Types of Chromatography
Gas
Liquid
Paper
Ion exchange
