Semiotics in the opening scene of pride and prejudice

In the opening scene of Pride and Prejudice you see horses feet, galloping strong and kicking up and wrecking the ground around them, this shows power and importance because they has mere disregard fort eh earth around them. The two men riding the horses are Mr Bingley and Mr Darcy the horses feet kicking up the ground strongly represents the how these two men are stirring up trouble in this quite if so boring new town in which they have arrived. The trouble and influence they cause is within the Bennet family regarding the Bennet sisters.

Mr. Bingley is riding a white horse showing purity and innocent, this could be a reflection of his character and personality with him being sweet and polite. This you see later on in the film with his ability to fall in live so quickly with one of the Bennet sisters. Where as Mr. Darcy's horse is almost a striking black. This shows darkness and and gives you a a warning of further occasions. the dark horse may show Mr. Darcy may be hiding something there may be a dark secret behind his calm look, you may even be able to say this reflect Mr. Darcy as a dark horse being someone you need to look over for whether that may be for good or bad reasons. 
The contrast of the colour difference of the two horses is another sign that the two characters of the men could be completely different yet could balance and counteract each other out.
