For a palette inspired by "пташка яка співає влітку в небі" (a bird singing in the sky in summer), I envision a harmonious blend of sky blues, vibrant sunrise or sunset hues, and the delicate colors of summer foliage. This palette captures the essence of a serene summer sky, the warmth of the sun's rays, and the lively spirit of a bird in flight.
