Our problem is that we have a very dark brown house, we want to go with a lite tan acrylic deck and then a sand pebble tec color. Can't tell which water line tile would be best. Keep with the browns or add some kind of neutral color or something else. I can't visualize it.
Your pool's elements don't have to match your house, or be a shade or tint of brown. The water, the deck and the edge tile can be part of a palette of colors that work together. Blue is the complimentary color to brown. Wander around on the 'net, or google "colors that go with brown," and find a scene or palette of colors that appeals to you, one that includes the brown of your house along with several related and complimentary colors. That might help you envision the possibilities. Below are some examples.
Once you have your palette, assign those colors to various object in your yard and the end result will look great. Bring colors from the pool elements to your house, and that will tie the two together. Ways to do that include: add chairs and chaises with slings that have all the colors of your palette. Sunbrella, which makes outdoor furniture fabric, has an amazing selection. Decorate the side of your house with "art" (wall hangings, yard art, etc) that "match" the pool's colors, and decorate your yard with objects that use some or all of the colors of your palette. Three glazed garden planters, for example, out in the landscaping; one brown, one tan one aqua (to support the colors of the house, deck and water).
There are all sorts of decorating tricks like that. The room below is decorated with many colors that are not shades or tints of each other, but all belong to a cohesive palette. You may hate the look of this room, or love it, no matter. It's just an example of a scene that consists of a color palette that works with brown (the curtains). Find a scene that you like and use that for inspiration for the palette you'll use for your pool and yard.
This rug has a palette of colors that would work. The brown of the house, the light blue-green for your water, the darker blue-green for your tile and the tans for your deck. (I don't know what color brown is your house, but you get the idea.)
The edge tile can be predominantly blue-green, to support the color of the water, but include "jewels" of color that tie the tile, deck and house all together.
You're only considering colors all of the same hue, just varying the tint: brown, light brown and sand. That's "safe," as they are bound to match. But that palette is not very interesting. Choosing a palette that includes
complimentary colors is much more interesting (browns and blues). Once armed with the palette, you go pick out tile and deck and pool finishes that belong to the palette.
Just one guy's opinion: that scene you posted is not all that great (in terms of color). The natural scene is really nice. The sand is a complimentary color to the ocean color. The pool water color kinda matches the ocean, and the pebble finish color kinda matches the sand. But the grey deck is completely out of place, as is the green of the grass. And there is no edge tile that might have been some help in tying things together. The colors of that scene are not pleasing, when viewed together. More to the point: it's not just about matching edge tile and house, but also making sure all the colors in your yard, your scene, work together.
TFP is all about keeping our pools from turning green, so maybe that's why you're not getting any takers here! 
) or pond, like Tahoe? That way it’s not a bright blue to contrast with the house but isn’t green either. But if you really like the green, green water then one of the tiles that is the same color as the pebble would work. Or that beautiful glass tile Dirk posted above.
