Most of my seeds are black but some are white. I have 3 different colors of flowers. Why are the seeds different colors?

This is an interesting question and there are two possibilities for the answer.
If the seeds are more off-white or beige than pure white, this is probably an issue of different varieties. Different morning glories can have different colors of seeds. Since you have multiple flower colors in the same garden, a few varieties probably cross-pollinated, leading to a mix of seeds on the same plant. If you plant them next year, you will probably have multiple flower colors again.
The other possibility is that the white seeds are not quite mature yet. The seeds start out white and then turn darker inside the pods when they mature. The immature seeds will probably not germinate well.
