I think you are giving yourself too many options and it is overwhelming you. Start over, clear your head and begin with a couple questions. What is your skill level and what would you feel comfortable making? What is their style? Are they traditional (log cabin, churn dash types), are they scrappy, or maybe modern (like an illusion top)? Now you have your comfort level, their colors and their style. The options are narrowing. The colors are a bit different. The first thing that jumps out at me is making a basic grey and burgundy top and using a complimentary shade of the orange as cornerstones and a narrow framing border. This would allow you to add it without it overwhelming (which is exactly what an accent should do). Please let us know what you decide. And, if you don't get some sleep, you won't do your best job! This should be a fun project - enjoy it!
