I'd be careful there wrt trying corals and peaches... you might bring in some genes for mud. I forget who/what is presumed to be the culprit - Iirc it is something associated with the genes for melon, which can show up in yellows, and therefore maybe some peaches. I don't know about coral.
Speaking of coral, 'Coral Majority' has a great color, but at 4.5" it's just barely a large (per AHS rules) flowered daylily and is somewhat plain apart from the glowing, hard-to-capture color. Mine is in shade, so I don't know if it has diamond dusting or not; the ATP database makes no mention of it, though.
