Using this palette

Built around a single strong contrast rather than a smooth ramp — two cool, dark tones standing in for the darkening field and sky, against three warm tones for the moon itself, because the actual visual event this references is exactly that: one bright warm disk against a cooling dark landscape, not a blended transition. Use the cool pair as the majority background and the warm trio as a concentrated focal area (literally a circular moon shape, or a CTA cluster) rather than spreading all five evenly. #1A1A2E and #3D3D5C both carry light or gold text well.
