Lookup field displaying results from another lookup field.

Hello,

I have 2 fields one being Colour and one being Finish.

If I have Colour: Arctic White, I want my Finish field to only show the options: Satin, Polished and Silk. But if I select the Colour Nero I want it to only show the finish: Satin.

I have created a many to one relationship from Colours to Finish, but how do I configure the Filter Criteria in the view?
