Select an Image:
We are assuming that an image is open.
Select "Colour Picker Tool":
Click on the “Colour Picker” icon from the tool box. You get a colour picker box with several options. In other words, a colour swatch box appears.
The only thing you need to worry about from this box is the selection of the radio button that says “set foreground colour” or “set background colour”.
This lets you fill the foreground or the background of the final image that you are working on.
Select the Colour:
Now you need to click on the particular colour in the image you want to copy the colour from. For your convenience GIMP provides you with a colour swatch. The colour swatch visually shows you the colour you are about to select for the filling in on the final image’s background/foreground.
Select "Bucket Fill" icon:
In Corel Draw X6 suite you will witness that a bucket automatically appears after you are done selecting the colour of your choice. However, in GIMP, you have to deliberately select the “Bucket Fill” icon from the tool box. When you are done filling in the colour you will yet again be provided with a a similar swatch box of colours for adjustment. Adjust the colour according to your needs.
Press Enter/Click on the Desired Area:
Once you are done, press okay. And there, the colour copying is officially complete.
