Ask Mr. Smarty Plants

To be honest, not all bluebonnet seeds are viable at all. In Nature, they put out so many seeds in the Fall that, given winter rains, many, many of those seeds will come up and provide new plants, which will then seed out the next Fall. From our How-To Article on All About Bluebonnets, you will get plenty of information about viability and scarification to increase viability, but not one word about the viability of different colors of seeds. You will also notice from that article that many seeds will wait in the ground for a few years for better growng conditions. The earth protects and insulates those seeds so that a period of inhospitable weather can still be followed by new plants when conditions improve. Generally speaking, with wildflowers the word is strength in numbers. The bluebonnets take this into their own hands, so to speak, by spraying all the seeds out into the ground and leave the rest up to Nature.

If you are interested in doing your own checking on the viability of seeds, see this article from About.com on How to Test Old Seeds. In view of your specific question, you should separate the seeds out by seed color and note on the plastic bag what color each one was.
