Inverse color selection?

[Wobblie]

Hi,

I have a bunch of dark brown colors surrounded by blue. The dark brown regions are not all uniformly dark brown. Is there a way to select a region within the blue outline (the predominantly dark brown) and color it all brown?


Thanks

The Fuzzy Select tool should do it, with suitable Mode and Threshold.

Thanks works like a charm.

spoke too soon!!

No matter how high I raise the threshold. I can seem to capture everything in the object.

Or conversely, if I select the darker blue outline then the various colors get incorporated with the shapes.

Thanks.

As far as I can tell (with the help of Gimp's analysis tools(*)) your brown areas are a uniform color, except on the edges (where pixels are a mix of the two adjacent colors, as usually done for anti-aliasing), and near the edges due to JPEG compression artifacts.

But the core of the areas is uniform. So, what non-brown color do you want to recolor? Because if you recolor the edge pixels, the edges will look pixellated.

(*) Namely

• Make a fuzzy select on the area
  
• Shrink the selection to get far enough from
  
  1. the 5x5 pixels due to your zooming in the screen shot
     
  2. The 8x8 "boxes" of the JPEG compression
