I grabbed this image of Albireo a couple of nights ago:
The bright orange star has a surface temperature of about 4,500K and the blue one a surface temperature a little over 10,000K, hence the beautiful colour contrast between the two of them. For reference the Sun has a surface temperature a little under 6,000K.
Albireo should be easy to find in the night sky right now so long as you don't live way down in the Southern hemisphere or in a city. Have a look to the east around midnight and see if you can find the constellation of Cygnus, the Swan, as shown on the star chart here. The same chart also shows Albireo (near the bottom). To the naked eye it looks like a single fairly unremarkable star.
