Unfortunately, this relies you on "eyeballing" the color and gamma. That should be good enough for web browsing, office tasks, and watching movies. But for professional graphics work, you'll need to buy a colorimeter and have it generate a color profile.

The max color saturation is determined by your monitor. If the monitor's colors are pale at max color brightness, you cannot fix that. You have to get a better monitor. The exception is if you've got an nvidia card. Many years ago for some strange reason, nvidia thought it would be a good idea...

The exception is if you've got an nvidia card. Many years ago for some strange reason, nvidia thought it would be a good idea to limit the range of output colors. Instead of showing the entire 0-255 range for R, G, and B, they limited output over HDMI to 16-235. They've since corrected this mistake, but every now and then it crops up again. If you think this is happening to you, here are instructions on how to fix it.
