[Change area filled with percent to solid colour?]

Many thanks, Joshua.

I am going to read some tutorials as well !

[Change area filled with percent to solid colour?]

I have filled an area with the paint bucket choosing a percentage. (since then I have saved and reopened the file.)  I now want to change this to a solid colour but it just fills each tiny segment between the percentage.  Is there a way I can do this?  I tried changing the tolerance but it fills too much of the image.

 

Thank you.

 

PS I confess I am completely overexcited with using Paint.net and haven't read any instructions properly!  I used to use Paint a lot in the 1990s at art college and it's bringing it all back to me!
