Dragon Templates (and Variants), Volume 1 - A to H, has 23 templates ranging from a -1 to +3 Challenge Rating (CR). The templates are light on detail, providing an introductory paragraph or two, a brief note on the physical changes that the template causes, and lastly the mechanics which sometime come with drawbacks. While some of the ideas are interesting and solid, they are not well developed and the CR adjustments do not seem to always align with the powers granted. The hybrid (half dragon/half something else) variant is especially sketchy but the albino, broken and glass templates have a considerable amount of potential.
If you use a lot of dragons in your campaign, or if you just want the ones that show up to be unique and interesting, these products will provide inspiration and a starting point for various unusual dragons but they are only a starting point, you will need to work out the finer details and balance them yourself.
