I have both Vanilla Treats and Cascade, and I am very picky about hair matches.
Lucky Clover is a very close match for Cascade, although it does not match 100% upon close inspection. Less picky restorers would probably say it's a match. Unfortunately I have used up my Unlucky Clover so I can't compare, but I suspect it would be even less a match since it is less vibrant than Lucky Clover and Lucky Clover is so close. Bear in mind that colors can fade over time if you are doing a partial rehair and not a full one; it is possible that a faded Cascade might match Unlucky Clover more closely.
Golden Delicious is similar to Vanilla Treat's color, but not a close match. Like Pineapple and Mango Tango it is too orange, and too translucent. Vanilla Treat's hair is matte. Perhaps Napalm (more likely, since it is matte) or Butterfly would be closer? I don't have either to compare, unfortunately.
