Is this true?

Someone told me if I brough a monitor for my MBP and did duel screen the colour on the external monitor will be different from my MBP screen. Also i been told Aperture does not show the colour the same on both screen they are different on each screen is this correct.

I have also found that printing from my MBP the picture is not the same as it appears on my screen

This has to do with the color sync settings for each display. Changing or adjusting it will fix it.

What the best way to do this as i am hopeless at it. Also how can i get my canon printer to print as it displayed on my screen through aperture?

 

[pinktank]

best way is finding a color calibration tool like color spyder and using that

You can't. They are completely different ways of displaying colour (transmitting colour with light shining through filters, vs. colour from light reflecting off of particles of pigment or dye on paper.

The best that you can do is to learn how colour calibration works, and make adjustments to both your monitor and your printer software so that the colour you get is reliably repeatable.

We can't teach you that over forum posts.

Suggest you hit the library or do some serious online study to understand what is needed.
