Replace similar colors with one nearest color

Hi,

An image I imported contains an area with quite a few different, yet very similar colors (different shades of the same red). I want to change the complete area to one single red tone. What's the most appropriate approach to this? Especially without loosing the antialiasing at the edges that surround the area.

TIA!

I'd probably use select by colour, or the magic stick select tool with a suitable threshhold (play with the mode in tool options, Hue might work best), and then feather selection and flood fill

The problem is tha the anti-aliasing pixels are also "different shades of the same red".

I would try something like: - use the wand selection with a large threshold to include also the anti-aliasing pixels
- shrink the selection by one pixel to exclude the antialiasing - bucket-fill

Liam and Ofnuts, thanks a lot for your replies. I got an acceptable result this way - I just thought that there was a special filter that would make this job a bit easier.
