Cheery red on that neck would be awesome.. but it might clash with the body colours maybe do a test on some scrap wood first to compare..
If you are using a water based stain.. like Clou from Blackbeardsden.. an easy way to get the flame to pop with minimal sanding is to wipe it on with a cloth,, then immediately wipe it off, almost wiping all off with a damp/wet cloth..
