Some further thoughts: In terms of minimums for 'inactive UI' components - they should really already have IMO a relatively high ratio as the provide a visual level of affordance to the end user. So things being greyed out etc until they are active/selected should be as high as possible - and then obviously higher when 'selected/active'.
