I am getting married in September in San Diego, and I am unsure about wedding colors. What do you think?

It is extemely hot in San Diego in September. My ceremony will be aroud 4 pm in a patio surrounding by pillars covered in ivy and the reception is indoors nearby immediately following the ceremony. I am so indecisive about colors, I have gone from coral, to red and now I have chosen "marine blue and white". If I were to keep this color what other color could I put with, maybe even just small accents of it here and there? Or if you could suggest even a completely different color, any advice is appreciated.
