Question

how to separate a mixture of color paints​

Answer 1

Explanation:

While it varies between retailers, the general rule of thumb is that if the paint has been custom tinted then it's not returnable or exchangeable. However, if you can prove it's a mixing error on behalf of the store, you can request a free replacement

Answer 2

Answer:

You can separate all the pigments from the binder or liquid part of the paint. Using a high speed centrifuge can make the pigmens separate as layers due to the difference in density.
