Answer: Negro artists must create art only about their culture and ignore criticism.
Explanation:
In this excerpt, Hughes notes that the reason N**ro art is not flourishing is because the artists involved were trying to be too white or too American and that this cannot work because it does not represent who they are.
He is therefore inferring that N**ro artists should focus on art about their culture instead of pandering to white influences and criticisms and this would enable them to gain more success in the field.
