I would request more clarification, but I have to go through another person, and do not have personal contact with the client. I am so confused though. First he says colorful, then in the next sentence he says flat color. Those are opposites in my mind. Below are my exact instructions.
Create 2 banners for them to pick from. Stylized text only with a colorful background. Just a flat, color background. Something in the Spring-ish colorway, but just a color should work
1 - 5 hours only !
2 - SAVE 15% !
Is it possible they mean 2 versions of 2 posters. The 5 hours only as well as SAVE 15% are the 2 posters.
The two banner options would be:
Version 1.) Stylized Text on colorful background
Version 2.) Stylized text or even plain text on a Flat color background
