Larger Colour Picker

[marblemsn]

Hello,

 

I am new to Prestashop, and I am totally lost.

 

My internet site is www.rajastones.co.uk. When you click on a category on the left, say 'Basins', a list of items appears, if you select a product, you are given details such as colour, price and dimensions etc. I need larger colour 'boxes'.

 

Can this be done, and how do I do it?

 

Any help would be appreciated.

 

Thanks
