I noticed that colours on Ubuntu look different than on Windows, on the same laptop. The problem is that when I use Photoshop in Virtualbox and I make a solid colour image in one colour, and when I view it on a host OS (Ubuntu), the colour looks different. I work as a web designer, and this bugs me, because stuff doesn't look the same.
Let me show it to you.
This is part of my website as viewed in Virtualbox Windows. You can notice that all of the green lines look the same. Top line is defined in CSS, and the shape below it is a PNG image. Colours are the same.
Now, lets see how that looks in Ubuntu.
The top line (CSS defined) is the same, but the image below changes its colour to a more vivid tone.
The screen is not the problem since this doesn't happen in Virtualbox on Windows, only on Ubuntu (host OS).
Is there any way to calibrate colours on Ubuntu, like it's possible on Windows?
I tried the Colours app in System settings, but the Calibrate button is greyed out, I can't click on it, and other options do not provide any calibration.
Since it's a laptop I can't do it manually, so it has to be done via software. I am using Ubuntu 14.04 LTS.
