Create 2 columns and populate variable data combinations

I hope you don't mind a mini novel:

Need to create a table based on 2 other tables.
The resulting table would consist of every combination (and vise versa) that the 2 source tables would create. For example:
Source data 1 located in column A (A2):
Blue
Red
Green
Orange

Source data 2 located in column L (L2)
Circle
Box
Triangle
Square
Rectangle

Both source data columns can have a variable number of entries.
Need to create the following data table on a different worksheet utilizing columns A and B
(Blue in col A, Circle in Column B in the example that follows):

Blue Circle
Blue Box
Blue Triangle
Blue Square
Blue Rectangle
Red Circle
Red Box
Red Triangle
Red Square
Red Rectangle
Green Circle
Green Box
Green Triangle
Green Square
Green Rectangle
Orange Circle
Orange Box
Orange Triangle
Orange Square
Orange Rectangle
Circle Red
Circle Blue
Circle Green
Circle Orange
Box Red
Box Blue
Box Green
Box Orange
Triangle Red
Triangle Blue
Triangle Green
Triangle Orange
Square Red
Square Blue
Square Green
Square Orange
Rectangle Red
Rectangle Blue
Rectangle Green
Rectangle Orange

In short: each combination of all the values from both columns would be represented in the new table.
The reason for this is to allow updating of a list to include new items and combinations of available products.
I've extracted the unique values from the new table. This works in a validation list dropdown on another sheet, where the user can enter a color, and an adjacent column will populate all the shapes associated with that color. The necessity of a macro is for the purposes of updating with additions and deletions from both data source tables. This macro can rebuild the table from scratch with each refresh. I can add a sorting provision, and code to adjust the named range fields.
I'm hoping that my approach to this is fundamentally sound, and workable. Just need a vehicle to make updating this workable. Other approaches would be certainly appreciated as well.
Thank you for your ideas.
