#### With Bash the last symbol looks very bad, like this

![oh-my-git](https://cloud.githubusercontent.com/assets/6009528/6031476/0b9bfe2c-ac00-11e4-898a-324a71be6cb5.png)

**A**: Unfortunately, I haven't find a way to tell bash "*print the next symbol using the background color currently used by the terminal*" and as far as I know [there's no way to achieve this result](http://unix.stackexchange.com/questions/1755/change-the-ps1-color-based-on-the-background-color#tab-top). Zsh is not affected by this issue, but bash is.

As a consequence, when printing the last symbol, oh-my-git has no choice but setting explicitly the foreground and background colors. Currently, the standard background color is black. This is unfortunate, because if the terminal uses a different background color than black, the result is bad, as showed in the above screenshot.

A smart solution is the one proposed by [@Sgiath](https://github.com/Sgiath): in the color palette set the first color (the one in the top-left corner) same as background color, like this

![oh-my-git](https://cloud.githubusercontent.com/assets/6009528/6039646/454c965e-ac69-11e4-8f80-37425181d04b.png)

This in fact sets the "black" color to the same color used as the terminal background.


If for any reasons you cannot change the palette, you can override the colors used to render the last symbol with the variable `omg_last_symbol_color`.

For example, if the terminal is using a gray background, you can add a

```
background=240
red='\e[0;31m'
omg_last_symbol_color="${red}\[\033[48;5;${background}m\]"
```

to your `.bashrc` and fix the issue by choosing the right value for `background`.

You can use

```
foreground=160
background=240
omg_last_symbol_color="\[\033[38;5;${foreground}m\]\[\033[48;5;${background}m\]"
```

if you want a more detailed control on the colors.

Finding the right value is not trivial. Please, refer to [this page](http://bitmote.com/index.php?post/2012/11/19/Using-ANSI-Color-Codes-to-Colorize-Your-Bash-Prompt-on-Linux) for a the 256 colors code table.
