Invert intensity (HSI)

Playing a little I found the XF86VidModeSetGammaRamp() function that allow to change the LUT of the rgb channels. The problem is that's useless... I want to invert the intensity, but leaving the colours as they are (so light blue will become dark blue instead of dark orange) ¿any ideas? | |

well this could be done in openGL, something like glBlendFunc(GL_ONE_MINUS_SRC_COLOR,GL_ZERO); maybe make a special RGB cable with the signal/ground swapped over for each analog color channel? Don't know if that would work! | |

No, that would simply invert the image. (green would become magenta) I just want to touch the intensity. Also, I'm using ratpoison so could not make an `always on top' window | |
