Changing one color - grit - 08-26-2017
How to change one color in the image with another?
RE: Changing one color - Blighty - 08-26-2017
Method will depend on the actual image. Two different types of images are 1) an image created by vector graphics which has pure colours and 2) a jpg which has a large range of colours.
One Method:
Make a selection on the colour to be replaced. Bucket fill with the required colour.
Another Method:
1. Create a transparent layer below the image.
2. On the image layer, make a selection of the colour to be replaced. Delete the selection.
3. Grow the selection by 1 or 2 pixels. Do Colour to Alpha, using the colour that is to replaced.
4.Switch to the lower transparent layer
5. Grow the selection by 1 pixel
6. Bucket fill the selection with the required colour - this still on the lower transparent layer
Yet Another Method
Use Colour > Map > Rotate Colours

I suspect you intend "change one hue to another one", a single color (R,G,B,T) change creates IMO a very strange look to an image (unless you are talking of a child drawing with areas filled with a definite single colour).

Color>Map>Rotate colors can work in many cases (it actually replaces a range of colors with another range of colors), especially if what you want to do is mostly change the Hue.
