why mostly all the corporate logos are in red,blue and grey color, is there is any specific reason behind it ? if yes why?

Blue instills trust, grey is a bland, authorative colour, and red gives a feeling of action.

Red, White and Blue!
(After all, it's Independence day in the US.)

And white is like grey, neutral, plus the whole 'pure' thing attached to it.
