I don't think so, red has a smaller wavelength than the other colors we see, but I don't think that could translate into us seeing it faster (whatever that even means).

It's pretty rare to see red in nature that isn't blood or fire, and when you do it's often on dangerous things (like those frogs in the amazon). Maybe red is so striking to us because red things in nature are things we need to pay attention to?

Red actually has a larger wavelength. Red is at ~600 nm, while green and blue are at ~500nm and ~400nm respectively. Red has a lower frequency though.
