You bought a ColorHug!
First, thanks. I really appreciate you giving Open Hardware a try. Second, please join the colorhug-users group and tell us what you think. All announcements about new firmware updates and new client code will also be done on the mailing list.
If you are using CD version 20120424 or older (or your own packages) then make sure that you choose Native whitepoint when choosing the screen target temperature. Newer versions of gnome-color-manager have been patched to use only the native whitepoint when colorimeter devices such as the ColorHug are detected. LiveCD versions 20120510 and newer are not affected.
Things you might want to do now:
- Check everything is working correctly
- Calibrate your device if you have a photospectrometer
- Make sure you have new enough versions of all the software if you don't want to use the LiveCD
- Check any frequently asked questions
Check the hardware
First, we check the hardware can be accessed. Insert the LiveCD and reboot, making sure you boot the CD when the BIOS screen shows. Then, connect the ColorHug and run:
$ /usr/libexec/colorhug set-leds green 5 200 200
This should flash the green LED 5 times.
Get latest firmware
Get up to date calibration matrices
Refresh and select calibration matrices for each
display type that match your display kind (using the default calibration
is usually good enough for most people).
Measuring a test patch
Hold the device against the screen and click the
Hopefully the color on the screen will roughtly match the sample color.
Then we can create a ICC profile.
$ /usr/bin/gnome-control-center color
