Well, darling, stars actually twinkle because of the Earth's turbulent atmosphere bending the light as it passes through. The color changes occur because different wavelengths of light get scattered by different amounts of atmospheric gases. So, next time you see red and blue stars, just remember it's just the universe playing dress-up.
Stars flicker all sorts of colors, and the color of the star tells how hot it is. For example, blue and white stars are extremely hot, red stars aren't very hot (but not enough for you to walk on), and green stars are in the middle.
Red stars can be smaller or larger than blue stars as there are two types of red star. Red dwarfs are much smaller than blue stars while red giants are much larger than blue stars.
No, blue stars are hotter than red stars. In other words, red stars are cooler. Think of it as fire. The red one is hot, but the blue flame is RAGING hot.
The stars in the Eridanus constellation vary in color, ranging from blue and white to orange and red. The color of a star indicates its temperature, with blue stars being hotter than red stars.
No. Red stars are the coolest. Blue stars are the hottest.

The sun is hotter than red stars but cooler than blue stars,
White Dwarves and Blue giants are both hotter than Red giant stars.
Red stars have the coolest surface temperature while blue stars have the highest surface temperature. NERD!
The 20 brightest stars in the night sky cover the range of star colors: Red, yellow white and blue-white. The single brightest star is Sirius, which is blue-white. Antares and Betelgeuse, both in the top ten, are very red stars, to the naked eye. And so on.
