First Timer: Product Inventory Table

Creating a Product Inventory database to keep track of all the promotional items my company has. So far I have three tables: Suppliers, Inventory, and Event. In my Inventory table I have the following columns (in order): Product ID, Product Name, Description, Logo, Color, Size, Total Quantity, Supplier, Event, and Storage. There are so many different styles of shirts that we have accumulated over the years that for every shirt style there are multiple sizes and sometimes multiple colors. So with that, I have choosen to add the size and/or color to the product name as well as in the size and color columns.

For example:

Men's Wicking Polo: Small                             S

Men's Wicking Polo: Medium                        M

Blue Crinkle Cut Paper                                           Blue

Purple Crinkle Cut Paper                                        Purple

Will this create a problem? I didn't know how else to set it up because it didn't think the database would recognize that five Crinkle Cut Papers are different colors (making it five individual products because of the colors), if the product name on all of them is the same.

One more: I tried to run some relationships like between the Suppliers table and the suppliers column under Inventory but it didn't work.
