Script-Fu -> Color-Only Invert
This is a non-adjustable script which renders a color-only inversion -- inverts the hues of the images but not the lightness values.
The color-only inversion is part of the "color-invert" script, which has a total of five functions:
- invert - color only
- invert - light invert
- invert - simple color invert
- invert - solarizer simple
- invert - vivid v-invert
