Howto change a color in gimp

[aartikel]1593273835:left:infofreund-21[/aartikel]Hi all, in this small tutorial i want to show you, how you can replace a color in Gimp.
There are several ways to change a color . It depends on the range of the color-value.
if you want to replace exact one color (for example white (FFFFFF) it is more easy, than replacing a range of colors (for example, a sky – which has more values of blue). At the end of this how to you find the whole tutorial as youtube-video.

1.) Replace exact one color:

In the following example image we have 2 colors:
color1 : blue   (Hex: 0000ff).
color2:  green (Hex: 30ec72).

Now we open the Rotate-Colors Dialog

The lower arrows are set to the color you want to paint the shack.

For example from blue to red:
