In the Layers dialog dock, below the area where layers are shown, left
click the icon that shows two rectangles, one on top of the other.  That
will make a duplicate of the selected (or only) layer, above the
selected (or original) layer.

To change the new layer's mode, find the Mode selector at the top of the
Layers dialog dock, left click where it says "Normal" and select
"Overlay".  The Opacity slider right below that starts at 100%, but can
be used to make the selected layer partially transparent if needed.

The Layers dialog dock is shown at the upper right in the illustration
on this page:

Hard to tell without seeing it, but increasing saturation may help (in
the colours menu). Unfortunately different colours may be affected at
different rates, so you may have to experiment a lot. Work in stages,
and don't overdo it - there's always undo.

Another method for bringing up color (and contrast), is to make a layer
copy of the (scanned?) original, and set its Layer Mode to Overlay.
This alone may not be sufficient; or, if it does /too/ much to increase
color and contrast, dial the new layer's opacity back until if looks
about right.  (I think Akkana Peck posted this method here years ago,
somebody did and I have gotten a LOT of mileage out of it.)

After the above adjustment, do Layer > New From Visible, and do further
work if needed on the new layer.

Some tools to try:

Colors > Hue / Saturation - The saturation and lightness sliders may do
useful things.

Colors > Levels - The default setting will let you drag a curve up and
down where and as needed, to fine tune brightness within specific
ranges.  Play with it, and remember:  Control-z is your friend, just
undo any changes you aren't satisfied with.  Also and maybe more
importantly, the Channel selector will let you work on Red, Green and
Blue independently.

The Colors > Map > Sample Colorize tool may also prove useful,
especially if you want to go as far as combining multiple, masked layers
to recreate the original image.  The Help doc for this tool emphasizes
/removing/ color and creating abstractions, but it can also make very
good guesses in transferring colors from a sample image to the one
you're working on.  Worth a shot, maybe.

There are SO many ways to go about tweaking color in images...
