Change the colours of the Polls Widget
For some reason, the polls widget does not have settings for its colours in the configuration dialog. It seems to pick up its colors from template variables instead.
Find or Add the variables
The variable that the polls widget uses for its text color is sidebar.text.color - if this variable already exists in your skin, you will find it in the group that it belongs to.
If it doesn't already exist, add it by copying this into the <b:skin> section of your blog's template (Template => Edit HTML).
<Group description="Poll Widget" selector="widget.Poll"> <Variable name="sidebar.text.color" description="Text Color" type="color" default="#2288bb" value="#2288bb"/> <Variable name="sidebar.link.color" description="Link Color" type="color" default="#2288bb" value="#2288bb"/> </Group>
Add new variables if they are not already present
Configure the variables
Once the variables have been added to the template, you can configure them visually using the template designer (Template => Customize => Advanced).
