* Blue-white: B-type stars emit a lot of blue light, making them appear blue-white to our eyes.

* High Temperature: The high temperatures of B-type stars are responsible for their blue-white color. The hotter a star, the more blue light it emits.

Important Note: The specific color and temperature can vary slightly within the B class, with B0 stars being the hottest and most blue, and B9 stars being the coolest and slightly less blue.
