Requesting image manuplators!

[Alessia Starfurr]

I'm trying to customize an image for a concept and I cannot seem to do it myself with Gimp so i'm asking around

http://www.hard-light.net/wiki/images/thumb/Sccain.jpg/500px-Sccain.jpg

I'd like to change all the Red on this image to a blue but keep the shading , I'm
 not exactly sure how to do that I have tried myself and only managed to change a few pixels.

 This is definlty not my art ,but I'd still like to use it as a concept.

I used GIMP to just change the hue.

I used GIMP to just change the hue.

odd that's exactly the same program  I was using to try but I got nowhere how did you do it color-->map-->hue?

[George]

l just used the paint tool with blue as the colour and hue as the mode.

[Alessia Starfurr]

so how did you change all the red to blue so fast?

[George]

Making the brush really big.

[Alessia Starfurr]

But how did you only change the red?

Grey has 0 saturation, so it changed the hue of the grey, just not the saturation.

I really need to learn how to use GIMP better

Greys have always confused me with their shenanigans too.
