I have plenty of images made up with the same color, just like those:
Now what I want is to change their "main" color from "#3d507d" to "#7C0A0A".
I tried to do that by changing the "hue/saturation" but with no success. (batch changing the hue/saturation is available with this gimp script :http://registry.gimp.org/node/23499 )
So, how can I change the color from "#3d507d" to "#7C0A0A" ? preferably with batch/scripting option?
I use GIMP / Inkscape / Photoshop. I prefer explanations in this order (most preferred GIMP)
BTW, I don't want to change only the "#3d507d" pixels, I want to change also the "gradiented"/"Edged"/"partly transparent" pixels to match the change to "#7C0A0A". - in other words - It should be looking good... Thanks.
