    I haven't been able to view any attached images on this site for awhile now, so I can't see yours.

    But my answer would be the same unless the images is particularly bizarre, or particularly simplistic.

    To colorize one element in an image, what I do is select the part I want to change with the lasso tool. You can grab is in pieces if it's easier and combine them by picking the "add to selection" option in the tool if you want. And if you make a mistake and include something you don't want, just switch to "delete from selection" and clean it up.

    Once you have the arrow (or whatever you want next time) then I'd use the "colors -> curves" tool to adjust the color. You can get any color you want by adjusting the red, blue and green curves.

    Keep in mind that I can't see any images you attach for some reason, so this is general guidance.

    The key facts to keep in mind when trying to make some part of an image "transparent" are:

    1. JPEG's don't support transparency, so you have to save as another format. I recommend using PNG instead, since it's cleaner than GIF's.

    2. In GIMP after you open a JPEG use "Layer -> Transparency -> Add Alpha Channel" to make it possible to save the transparency info you add to the image.

    3. To make something transparent, just select and delete it.

    4. Save as PNG or XCF format to preserve the transparency info.

    Colorizing high contrast photographs takes much time and it is work expending undertaking. In any case, it is exceptionally fascinating. I was rehearsing this for three or four months
