Anyone can tell me the name of the blue blackground? Thanks in advance

You should be able to find it here: http://wowprogramming.com/utils/artbrowser/Interface

Or if it's not there, check out this: https://github.com/Gethe/wow-ui-textures

It's more up to date, even has a branch for Warlords of Draenor.

If you have any idea where in the UI the texture is displayed, simply looking through the many, many textures bundled with the game is a really inefficient search method. I'd suggest looking at the actual default UI code instead -- in this case you know that the texture is used on the friends list, and you can assume based on observation that it's a highlight texture (since it appears when you mouseover the frame, and disappears on mouseout) so you can just look in the file that creates the friends frame, and find out in much less time that the highlight texture for those buttons is:

<HighlightTexture file="Interface\QuestFrame\UI-QuestLogTitleHighlight" alphaMode="ADD" parentKey="highlight" />

It was not what I was looking for: do you remember the background that appears in the menu at the mouse hover?

What Phanx posted is the correct texture. The reason it is blue is because of this line in the OnLoad script:

self.highlight:SetVertexColor(0.243, 0.570, 1);

That texture is gray scale so you can make it any color you want with SetVertexColor. There is a texture that is already blue available but you won't be able to get the same range of colors with SetVertextColor using it: Interface\FriendsFrame\UI-FriendsFrame-HighlightBar-Blue

Very well. And if I want make transparents instead of blacks the texture outer colors?

If you can see by Phanx's post in xml file they use alphaMode="add". In lua you can do this with Texture:SetBlendMode("mode"). So SetBlendMode("ADD") should make the dark areas transparent.
