Buttons for the navigation bar....

I have attempting to create buttons for the website. I wanted to use solely type so that each time the type was clicked on, that type would then enlarge and leave the rest of the text as other optional buttons. I found that this resulted in the navigation being too long so I decided to experiment with what it would look like if I used the format of the buttons which are presented on the first page. I think this looks more structured and still works within the format I wanted....

I am going to use the second format, the type is far more legible when it is written in black with the coloured box around the edge to indicate the colour coding system being used throughout the product range.
