My laptop, a Thinkpad T430 with Intel HD4000 graphics, shows pretty desaturated colors by default. On Windows I can just increase saturation using the Intel Graphics and Media Control Panel to get extremely lively colors. Is there any tweak/application that I can use to get similar results in Ubuntu?

If you're experiencing problems on an external monitor over HDMI, try this: http://askubuntu.com/a/640153/109848 – namuol Jun 23 '15 at 21:59

this can be made with xrandr, first identify you video output running "xrandr" and look into the output sor something like this:
DVI-I-1 connected 1600x900+1600+0 (normal left inverted right x axis y axis)
in my case, my output is DVI-I-1, now i run "xrandr --props" to know what properties can i change.
scaling mode: None
supported: None, Full, Center, Full aspect
color vibrance: 180
range: (0, 200)
vibrant hue: 90
range: (0, 180)
non-desktop: 0
range: (0, 1)
link-status: Good
supported: Good, Bad
to change the saturation, in my case (Old GeForce GT 520), i run the following:
xrandr --output DVI-I-1 --set "color vibrance" "180"
Hope this works for all you guys. (same response: how-to-adjust-screen-settings-contrast-color-saturation-etc)

There is gnome-color-manager
(Ubuntu Repository): from a console (xterm is fine) do sudo apt-get install gnome-color-manager
. It should also run with other window managers but is a bit heavy.
Let me know if you solve, good evening.

Gnome Color Manager only allows me to install color profiles, and I don't have a calibrating device to create custom ones. Still the color profiles for the T430 that I have found on the web only give my screen a warm or cold tint, without affecting saturation. – Knef Ekbom Nov 02 '13 at 22:22
