The red wine Burst looks nice if you have a really interesting grain to show off. Most mahogany isn't going to be all that interesting grain wise, so I'd probably lean more to the Ghost Pepper color.
Also, just another personal preference thing - I have several basses with very interesting wood grain that have a satin or non gloss finish and to be honest, I think they would look better in high gloss. For example, here's a pic of my Warwick Vampyre in transparent satin blood red over quilted maple...

Looks nice, but I think the quilted grain would pop more under gloss.
My Pedulla that I just recently sold was vintage cherry burst over flame maple, you can see how much more the grain pops under gloss...

Even the relatively boring swamp ash grain on my Fender Jazz comes alive with a gloss finish...

Just some food for thought as you look at finish types and colors and wood grains.
