Table schema:
CREATE TABLE ref_colors (color_code VARCHAR, color_description VARCHAR); CREATE TABLE products (product_name VARCHAR, color_code VARCHAR)

Question: What is the name of the product with the color description 'yellow'?
SQL: SELECT T1.product_name FROM products AS T1 JOIN ref_colors AS T2 ON T1.color_code = T2.color_code WHERE T2.color_description = 'yellow'
