As there is no theme editor in TM2 yet, you can edit the relevant .tmtheme file (which is an XML plist file) directly in TextMate.  The setting for the colour of invisibles will be in the first block called "settings".  The key you are looking for is called "invisibles", as below:

<dict>
<key>settings</key>
<dict>
<key>background</key>
<string>#0F1110</string>
<key>caret</key>
<string>#F8F8F0</string>
<key>foreground</key>
<string>#F8F8F2F0</string>
<key>invisibles</key>
<string>#888574F0</string>
<key>lineHighlight</key>
<string>#3E464354</string>
<key>selection</key>
<string>#C16217ff</string>
</dict>
</dict>

The colour codes can also have a value for the alpha (transparency) appended to the usual 6 digit hex RGB code, which is why they look a little weird!   A little experimentation with the alpha value for invisible seems to show that TM2 is ignoring it - not sure if Allan can shed any light on this?

Is it possible to change the color of the characters used for invisibles?



I don't know about TM2, but in TM1 it's under Preferences->Fonts & Colors.
