After adding an IMAGE texture to an object, is there a way to adjust/change color in Blender in order to keep from having to delete the texture image, adjust/change color in GIMP, then add the new texture image to the object?
For example, if I create a texture image with light to medium yellow brown then add it to a tree object, then I decide the color should be more of a green brown or maybe the yellow brown should be darker, can these changes be made directly in Blender after the texture image has been added to the object?
