What color petals should i get for the aisle?

My colors are deep red (almost burgundy), navy, gold, with a hint of blush. I’m ordering 5,000 petals from Costco to scatter down the aisle. They have “red” or “white”(ivory).

I would definitely prefer red but I’m worried the red would be too bright, but I have no way of knowing the true color until the arrive the day before the wedding. Should I just do ivory? Does it matter? The red in my wedding is really an accent, bridesmaid dresses are gold.
