SQLBuilder how to define multiple OR conditions?

This is a really handy utility for building dynamic SQL in Dapper but I can't figure out how to do this.

SQL I want would be something like this:

SELECT * FROM Product WHERE (Color = "Red" OR Color = "Black") AND (Price > 100 OR Quantity > 3)

The issue is that it just aggregates all the ANDs together and all the ORs together. Assuming there is no way to do this currently would it be possible to have a mechanism to do this by passing a null to the Where( ) method? So for example:

sqlBuilder.OrWhere("Color = @p1", new { p1 = "Red" });
sqlBuilder.OrWhere("Color = @p2", new { p2 = "Black"});
sqlBuilder.Where(null); //or sqlBuilder.Where("AND") maybe? 
sqlBuilder.OrWhere("Price > @p3", new { p3 = 100 });
sqlBuilder.OrWhere("Quantity > @p4", new { p4 = 3});

Start by locating SQLBuilder and its Where and OrWhere methods, then inspect how conditions and parameters are currently aggregated. Define the grouping behavior needed for the two parenthesized OR expressions and verify it with a test matching the SQL example; done means grouped conditions produce the intended AND/OR structure.
