Colorizing an image
Ok, so I know how to recolor an image using layers, fill bucket and hue mode. I am trying to color the bright pink flowers to peach:

But the flowers just turn out orange, I'm assuming because the pink is too bright and is showing through? I also tried converting the image to grayscale first before coloring, but that didn't work either.

Someone please help! This is for my wedding invitations and I don't have a lot of time.

RE: Colorizing an image
In Hue mode you don't change the Saturation, just the Hue. Try to use Color mode, which is Hue plus a little bit of saturation.

Another method to replace a color: set the foreground color to the color you want to replace, make sure the layer has an alpha channel, and paint in "Color Erase" mode. This will turn the color to transparent (and some other color to partially transparent. Then set the foreground color to the new color, the paint brush to "behind" mode, and paint over the areas you erased (in "behind" mode the paint only fills the transparency, so it won't "spill").

The image you posted is rather dirty, full of JPEG compression artifacts, and quite small if it's intended to be printed (about 2.5"x2.5" if printed at 300DPI). Is this the one you are working with?

If that posted image is your only copy

Yet another option is try using the "Rotate Colors" filter
Peach is kinda orange/yellow...

1. google image search "peach color" for a referencec (see my example below)
2. Duplicate your image layer so you're working on a copy
3. Colors > Map > Rotate Colors...

Then change to the settings to look like the below picture. Where the "From:" circle is the range of colors you want affected.
The "To:" circle is what you will fine tune/toggle around.

If the color change is too strong, in the layer's window you can change the opacity of the top/duplicated layer.

RE: Colorizing an image
Need to define which bits you want to change (just the big flowers or...) and also what is peach?
The standard crayola peach is RGB 255,203,164 which you can put in the change foreground color dialog.

All those methods mentioned before have snags, Changing the Hue also Rotate Colors will globally alter other colors in the image.
Color erase works well, but you have to be careful, adjacent colours will partially erase if you stray into them.

One of the problems is what Ofnuts referenced, the image is dirty. What might look like one colour is a mix, plus jpg artifacts.
You should see on this screen shot
Again the image is small, not so good for printing also looks like it originally was a vector image.

For a beginner I think a straight selections with the fuzzy select will be easiest and from the type of image give a reasonable result.
everything on one screenshot.
Set the threshold to around 30
Set the mode to add and go around selecting the bits you want to change.
Then grow the selection by 1 pixel and fill.
Then it depends how keen you are, paint out with white any areas that touch and should be separate.
