For Seedfork's purple, I would suggest a Moldovan cultivar such as Mephistopheles. But it really is difficult to make suggestions without any other detail, such as scape height, size, and bloom season.
For Seedfork's red, I am wondering if this could be Vivid Heart.
Seedfork, are you sure your second yellow isn't MARY TODD? She's a very waxy-textured flower, with top heavy budding as shown.
