How to change this map's color into this?

Post #1by rl90599 » 30.06.2020, 15:20

Hello, I am making a Voyager 1 map of Jupiter, but there is one problem, the high-resolution map was yellow-greenish, and I was unsatisfied with it. Luckily, there is a same map like the yellow-greenish one but with a brownish color. But, that map was low resolution, was in 2 separate pages and was scanned. How do I change the color of the yellow-greenish map to a brownish color like the one down here:

If you don't know what the yellow-greenish map looks like, here it is:

By the way, I use GIMP.

You can use the Hue-Chroma or Hue-Saturation or Color Temperature to adjust the colors, although the yellow-greenish is closer to the real color than the brown color.
You'll never know how much I'll hurt inside. Also, did you know that cashews grow on top of apples?

basically you can not

However

you can desaturate the red and yellow
add some cyan to the image

and lower the contrast

and maybe get close
