you asked. Most hardware stores will have it. If you want something closer you either go to JD and pray they sell you something that matches, or take a part to a local autobody paint supply and ask them to match it. The latter is the best solution because not all batches of paint will be the same, and it fades with exposure to light.
Don’t go to a paint store to find a color match. Go to an auto body shop, as their employees know how to match colors better than paint stores, plus their paint will be of a better quality. You will get what you pay for, as it may be more expensive.
