Preheat oven to 350 degrees. Spread almonds on a rimmed baking sheet; toast until golden and fragrant, about 12 minutes. Let cool completely.

Transfer almonds to the bowl of a food processor; add flour, salt, and cinnamon. Process until nuts are finely chopped, about 1 minute.

Beat butter with confectioners' sugar on medium speed until fluffy, about 4 minutes. Add vanilla; beat until combined. Slowly add almond mixture; beat on low until just incorporated.

Line baking sheets with parchment. Using a 1 1/2-inch (1-tablespoon) cookie scoop, drop dough onto prepared sheets. Bake, rotating halfway through, until edges are just turning golden, 14 to 16 minutes. Transfer sheets to a wire rack; let cool completely.

For each desired color, place 1/2 cup fruit with 1/2 cup confectioners' sugar in food processor; blend until smooth and evenly tinted. (Sugars can be stored in airtight containers up to 1 month.) Sift tinted sugar over cookies as desired. Cookies can be stored in an airtight container at room temperature up to 1 week.
