Will Zinnia seeds grow flowers that are true to color?

I am slowly harvesting the seeds from my many zinnia flowers, which are of a taller variety.

I have about 7 different colors that I grew from Burpee seeds.

So I am trying to keep the different colors separated for the most part, except for a small number of mixed color seeds I've mixed up evenly.

But then I began to wonder about whether they will be true to color? In other words, I have many zinnias of the same variety growing together, and they have certainly been pollinated by bees coming from zinnia flowers of different colors landing on other flowers of different colors.

So, when I collect seeds from a red flower, will they all be red next year, or will they be a different or mixed color, since there are different colored zinnias all around, and I have no control over which flowers the bees or other pollinators are transferring pollen from?

Or will the colors be the same as the color of the flower that the seeds came from, regardless of mixed pollination?

I don't really get enough summer heat to make them truly happy and only grow them occasionally, but -

"Zinnias will cross-pollinate. Gardeners should only grow one variety at a time to save pure seed, or isolate varieties by 1/4 mile. "
