Gimp does not have a colour eraser "tool". It does have a colour to alpha plugin though. By default the plugin will remove the selected colour from the whole image. To constrain this you will need to make a selection befor running the plugin.

Hi there.

Is there an eraser tool that will erase only a specific colour? That is, that will selectively erase only those points it passes over that are of a particular color. For example, you have an image with a line on it that you don't want. You use the dropper to pick up some of the line colour, then tell the eraser to erase only that colour.

Similarly (and related to my previous question about filling outlines on transparent layers) is there a cousin to the fill tool that selects a region based on colour? Just as the fill tool works out towards a colour boundary and then fills inside the boundary, so this tool would work out to a colour boundary and then select the area within it.

Other (much more primitive) "paint" programs have such tools, but I haven't located them in the GIMP.

As I use the GIMP more and more, it is becoming clear to me that some simple things have very complicated solutions - apparently the price to pay for having very simple solutions to complicated things :-)

/Select/Select by color

or try the Fuzzy Selection (AKA Magic Wand tool)
