Sprite gives the candies a faint acidity that helps them taste like the real thing, and to that same end I've made suggestions for how to flavor each color to match the classic flavor line up. But don't hesitate to experiment! No doubt you'll think of all sorts of fun, alternative flavor pairings limited only by the extracts or freeze dried fruits you can get your hands on.
I don't provide measurements for the food colorings, as the quantity needed varies from brand to brand, but as a general rule: easy does it! It takes only a tiny amount of gel paste or a drop of liquid coloring to get the colors just right.
If you can get a few pairs of disposable gloves, you'll save yourself a lot of hand washing and the annoyance of trying to knead the candy inside a plastic bag or between sheets of food wrap.
Note: All measurements are in weights, as volume measures can be very imprecise. I strongly recommend using a scale for all pastry projects. Serious Eats' recommended kitchen scale is the Oxo Good Grips Scale with Pull Out Display.

Bloom the gelatin:
In the bowl of a stand mixer, combine gelatin and Sprite. Whisk with a fork to combine; let stand five minutes. Meanwhile, bring a small pot of water to a boil. Place the bowl of gelatin over hot water and stir occasionally until melted.
(If using a hand mixer you can use a water bath too, or use a microwave safe bowl and zap the gelatin at five second intervals until melted.)
Make the sugar paste:
Fit the stand mixer with a paddle attachment. Mix melted gelatin/Sprite mixture with about two cups of powdered sugar and until it forms a sauce like consistency. Add in the salt and continue adding powdered sugar, a few cups at a time, until a dough forms. You may not need all of the powdered sugar; use any excess for rolling out the paste later.
The finished candy "dough" should be thick, malleable and not particularly sticky. Turn the dough out onto the counter and knead (using more powdered sugar to prevent sticking if necessary) until smooth.
With a knife or bench scraper, divide the dough into six portions, or however many colors/flavor portions you plan on having.
Place all the dough portions into a zippy bag, or wrap each in plastic.
Flavoring and coloring the candies:
If you have disposable gloves, this next step will be easy, just like kneading bread dough. If you don't, you'll knead the dough between two sheets of plastic wrap or through a large zippy bag.
Take one portion of dough, unwrap, and make an indentation in the center with your fingers. In the well, place a few drops of the desired extract/freeze dried fruit powder along with a touch of food coloring (if using).
Knead the dough until the color is perfectly uniform, about 3 minutes. Taste a pinch of the dough and adjust the flavor if need be.
Rolling and cutting the candy:
Have a parchment lined sheet tray ready. On a surface dusted very lightly with powdered sugar, roll the dough out with a pin to 1/4" thickness. Use a heart shaped cutter to stamp out the candies. You can gather and reroll the scraps as many times as you like.
Transfer the cut-outs to the prepared tray and set aside.
Repeat the flavoring/coloring, rolling and cutting process with remaining dough.
Drying the candy:
Let the cut-out hearts air dry, uncovered, for at least 24 hours. If you have pets or kids, be sure to set the trays somewhere out of the way.
After 24 hours, sample one of the candies. If the texture is to your liking, you're done! If you prefer a harder, crunchier texture, flip the hearts over to expose their bottom sides and dry another 24 hours.
In either case, decorate the candies (or not) with a food pen. Store in an airtight container, indefinitely.
