Could two stars of equivalent mass/size form a binary system and be different colors?

I have an idea for a planet that orbits two Suns. These Suns slowly orbit each other, have equivalent masses/sizes, and while one is slightly red, the other is slightly blue. A year is about as long as Earth's, and a sun cycle (day) is 24 Earth hours. The rotation of this planet causes eight hours of night time, say, from eight to four o'clock on equinoxes. One sun would rise at four o'clock and set twelve hours later, and the other would rise at eight o'clock and set twelve hours later. Is this system possible? I also wonder how seasons would affect the sunrises and sunsets if the planet had a tilt about the same as earth, but more important is how plausible this planetary/star system is. I'm a little bit worried about the stars, I read somewhere about red stars being smaller and blue stars being larger.
