Please suggest a vibrant and cohesive color palette of exactly 12 colors for a sunset valley mural that emphasizes a high desert landscape. The palette should encompass the richness of sunset hues while providing a balanced spectrum for depicting various elements within the scene. The colors should be as follows: A range of 4 oranges from a soft, pastel peach to a deep, fiery burnt orange to illustrate the dynamic sunset sky. 3 purples from a gentle lilac to a rich royal purple to capture the deepening twilight. 2 vivid reds, one lighter like coral and one darker akin to wine red, to represent the sun's last rays and flora. 2 blues, one a clear sky blue and the other a deep twilight navy, for the sky transitioning to night. 1 lush green, a versatile shade that can represent foliage under various lighting conditions. This curated selection should allow for the creation of a visually stunning and harmonious mural that captures the essence of the high desert valley as day turns to night.
