It would depend what the black pot was made of. Assuming ceramic and both pots have the same surface area, then the silver pot would cool quicker; silver is a better heat conductor than most ceramics.

Why does hot water cool quicker in the first 5 minutes?
This is because of newtons law of cooling, the rate that the water cools is proportional to the difference between the temperature of the water and the temperature of the surroundings. So, as the water is hotter it cools faster, as it cools down the rate of cooling decreases.
Why does ice melt faster on black than white paper?
black absorbs heat, giving it more heat to melt the ice
Why tea is cooled more rapidly by blowing?
Hot vapors are rising from the tea. When you blow these vapors away more can rise faster to replace them. Thus more hot vapor (and thus more heat) can leave the tea while you are blowing than when you are not and the tea cools faster.
Does the temperature of water affect how rapidly salt will dissolve?

Does hot water get colder faster than cold water?
Yes ,the higher the temperature gradient between the hot water and room temperature, the faster it cools. However, that does not mean that hot water will freeze faster than cold water (a common urban legend). If you have water at 50°C in a room at 20°C, it will cool from 50° to 40° faster than it will cool from 40° to 30°.
Why does sugar dissolve faster in hot tea than in cold water?
Hot fluid has a higher ability to dissolve solids like salt and sugar. This is how Rock Candy is made. You add as much sugar as possible to hot water, then when the water cools down, the sugar solidifies to everything it can. Hot water is just able to do this.
