Replace parts in background color with foreground color?

[littlebigman]

Hello,

 

I looked around the menus, googled, and checked the archives but didn't find the answer.

 

Is there an automatic way to tell Paint.net to replace all the bits in the picture that are displayed in the background color with the foreground color?

I vaguely remember that PaintShopPro allowed this, although the user had to use the eraser.

 

Thank you.

Select all of the secondary colored pixels with the magic wand tool (use the Shift key to make a Global selection).  Press the backspace key.
