Editing Brighter Shores:Color masking (section)

==Doing it in software==
In image manipulation software such as GIMP these transforms can be applied by changing the color balance, lightness, and saturation of the texture image, on the area specified by the mask image. 

The above images of Coarse Posts were obtained by tweaking the values of the colour manipulation parameters until the colours of the resultant image matched a lower resolution screenshot of what the output should look like. However, once the color transform has been determined for one image, the same transform can be applied to other images. In this example, the Rugged, Average, Fine, Sturdy, and Perfect Posts for each of the 3 wood types also use the same colour transform as the Coarse Posts shown. The images created will not be perfect pixel matches to the game, but they can be close enough that people won't be able to tell the difference unless they really compare them side by side while zoomed in a lot.

What this doesn't do is allow us to know what the transformations are for an entirely new color.
