Hey folks,
((thought I already sent this but I can't find it. sorry if repeat))

In selecting areas by color (whether contiguous or not) I can set the threshold to get more or less colors similar to the exact color I click on. I can then drag a color from the toolbar and drop it on the image and it will fill in those selected areas, and this is really cool....

Is there a way to make the color I fill those areas in with change in relation to the colors it's replacing? For example, if I select a range of greenish colors, is there a way I can replace it with a range of blueish colors instead of just one particular blue?

Thanks, Cheers-

1. Desaturate the selected area.
2. Use the Bucket Fill tool with the blend mode set to Overlay or similar.

Sounds like a case for the LEVELS dialogue to me, and then some playing with the CHANNELS and adjustment of light, dark and gamma settings on each of them.

Here's a different approach to getting the effect you want, based upon the proposition that it will take more (perhaps much more) time to get the effect you want by replacing the colors in the pixels you want to change with new ones, than it will by modifying the existing pixels,

1) Open the image you wish to modify

2) Select the areas of your image where you want to change the colors, and copy the selection, and paste it into a new layer filled with tranparency.

3) Open a new image filled with transparency, and copy the layer you made in step 2 above to this new image.

4) Using the color balance and hue saturation dialogs, make the adjustments want to the colors in the image you created in item 3.

5) Copy the entire modified image and paste it into a new, transparent layer in the original image.

6) In the new layer in the original image, select the background by color, and invert the selection.

7) Leaving the selection intact, select the base image as the active layer; cut out the selection.

8) Merge the layers together.

While fill doesn't work, you can easily do what you want by selecting a big brush, setting the mode to hue, and brushing across the selection. Hue leaves the saturation (how much color) and value (where on the black-gray-white scale), alone, and just changes the hue (what color). If you get a big enough brush you can do it in one click. I often select an area like for instance, a friends face with the magic wand, and change the color while retaining all the highlights and the brightness.

It does work.

What you just did, is fill.

If you want to fill, use the fill tool. Set the mode to hue of course, and shift-click on the desired area ( or just select the option 'fill entire selection' and click normally)
