Yet another tub caulking question (sorry!) -this time about color

Hi folks-
I know the "tub & shower surround caulking question" has been done nearly to death, and I've googled around, but I've got a specific question that I could use some advice on.
The new tub/shower surround I put on is nearing completion. The tile (8"x10" marbled off white) is set and the mortar is setting up. Next weekend I'll grout with a "Natural Gray" Polyblend grout. It's a fairly dark gray.
My question is how to handle the two vertical corner seams. While the tile is reasonably well set and the lines matched up well enough to please my eye, I did screw up on a few of the corner cut pieces, so I want to hide about 1/4" on either side of the vertical seams.
So I'm looking at caulks. I don't want to use clear caulk, because one could see my errors. A white caulk would look bad forming a seam against the dark gray grout.
I found at HD a product called "Color Caulk" (made by Color Caulk Inc.) but the closest they had was "Delorean Gray" which is much lighter than the color of the grout I'm using. I went to their website to see if I could find and order a closer match, but oddly this product (the Color Caulk) isn't there! Everything else they sell (mortar, grout, adhesives, etc.) is listed, but not that product.
The Color Caulk is a latex sanded caulk, with fungicides. In this day and age is latex caulk really still appropriate for bath use? I'm used to using silicone based products these days.
Any thoughts here? Experiences, links to good products for this use, and thoughts on latex versus silicone appreciated.

most manufacturers make a color matching caulk for their grouts. if you cant find some for your grout, dont use that grout. get other grout with a similiar color and matching caulk.

You really should not be talking about your caulk on this newsgroup. You'd be better taking it to alt.sex.
