How many colors are in the sky?

The sky can display a wide range of colors depending on various factors such as the time of day, weather conditions, and atmospheric phenomena. During sunrise and sunset, the sky may showcase vibrant hues of red, orange, pink, and purple. In contrast, a clear daytime sky typically appears blue due to Rayleigh scattering, while overcast or stormy conditions can lead to grays and darker shades. Thus, while there is no definitive number of colors, the sky can exhibit countless variations.
