Leo, the Lion constellation, features stars of various colors, but it's not about one single color for the whole constellation. Here's a breakdown:

* Regulus (Alpha Leonis): The brightest star in Leo, Regulus is a blue-white star. It's a hot, massive star.

* Denebola (Beta Leonis): Another prominent star, Denebola is whitish-yellow, slightly cooler than Regulus.

* Other stars: Leo contains various other stars, ranging in color from yellow-white to orange, and even a few red giants.

So, Leo's stars are a mix of colors, not just one specific hue. When you observe the constellation, you'll see a blend of these colors, giving it a rich appearance.
