Angry Melamine Paint colour Shift

We accidentaly stained our laminate covered bathroom vanity by placing a corrosive toilet bowl cleaner bottle on it. So we decided to refinish with a melamine paint from Home Depot. They recommended CIL Melamine paint and sealer. CIL is a Canadian company, very old with very good products. We sanded, and also primed with the recommended CIL product. After the requisite 16 hours of drying we painted with the Melamine Paint. It went on reasonably well with a small sponge type roller and dryed to a nice hard finish that was somewhat darker than the the colour we had selected, but quite pleasing. As expected there were a few areas which had not completely covered so rather than recoat the whole vanity we just touched up the problem areas again after 24 hours of drying.
Strangely, the touched up paint from the exact same can was now a much lighter colour than the original. We assumed it would blend in as it dried. Well, it has not!! We cannot believe what has happened. It is now 24 hours since the retouching and the new areas are significantly lighter than the first coat. Even the drips on the can are different colours! For both coats we stirred the paint thoroughly and were scrupulously clean. There was no chance of contamination whatsoever. What could possibly have happened? What do we do now? Certainly we will return the paint to Home Depot, but what if the same thing happens again?

You may not have mixed the paint as well as you thought although about 25 yrs ago I worked for a company that was painting a new large apt complex. I don't remember who manufactured the paint [wasn't name brand] but for whatever reason we had to spray and roll 1 color and brush another color for the paint to blend

My advice would be to lightly sand and completely repaint the cabinet. It is doubtful that paint out of another container would match. Also enamels can be difficult to touch up.
