A shiny grey which quickly fades into a duller tone when exposed to the air due to its reaction with oxygen.
The formation of a silver metallic color on sodium metal is a physical change. This change is due to the reflection of light by the metal's surface, and the silver color is a property change and does not involve a change in the chemical composition of the sodium metal.
Sodium astatine does not exist, as astatine is a halogen element while sodium is an alkali metal. Sodium is typically silver-white in color, while astatine is expected to have a dark, metallic appearance.
Both sodium oxide and sodium chloride contain sodium ions which exhibit a characteristic yellow color when burned. This color comes from the emission of energy as the electrons in the sodium ions transition to lower energy levels. Thus, both compounds burn with a yellow flame.
The color of a flame is determined by the specific metal ions present in the substance being burned. In this case, both sodium chloride and sodium nitrate contain sodium ions, which are responsible for the yellow color observed in the flame test. When these substances are burned, the sodium ions are excited and emit yellow light, resulting in the same color of flame.
Oh, sodium is a very soft grayish metal, it absorbs moisture from air and also reacts with carbon dioxide present in air. So sodium is kept stored submerged in a non-reactive liquid, like a petroleum distillate. As the metal is cut by metal knife, or a glass rod or anything, that cut will determine the surface texture.

All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
The color (yellow) is due to the metal ion (sodium), the other element does not participate.
