The photosphere and chromosphere are typically described by the following characteristic:
their visible colors, such as red or yellow.
- The photosphere emits most of the Sun's visible light, giving it a yellow color when viewed from Earth, while the chromosphere is often associated with a reddish hue due to the prominence of hydrogen alpha emissions.
Other characteristics mentioned, such as plasma composition and energy travel, are important in a broader context but are not as typical in the initial descriptions of these layers.
