I am using Ubuntu 18.04. My graphics card is AMD Radeon R3 Graphics.
This a screenshot of my screen.
Clearly the blue circle appears purple. Why is it happening and how to solve it?
My system is thoroughly updated and upgraded.
Or is it that I am actually color blind?

Is the Night Light mode turned on in Settings > Devices > Display? If so, does turning it off fix it?

Yes night mode is turned on, checking it turning off.

Wait... you posted a screen shot to show us the color of your screen? This is the one time you are allowed to use a camera to take a picture of your screen, screenshots are going to be rendered by our computers as completely normal.

Since version 3.24, Gnome has a built-in blue light filter called Night Mode. It is now almost a proven fact that exposure to blue light in night-time disrupts our sleep pattern. Night Mode is there for that reason: to limit your exposure to both bright and blue light from the screen. It works by applying a red hue upon screen. So when it is turned on, blue colour may look purple (this is the case here, see comments on the question).
Go to Settings > Devices > Display. There you can customize Night Mode by setting activation time or controlling red-level. Or you can disable the feature altogether.
Although not related I am always curious about it? How to pronounce "Gnome"? Is it like "Go" for "Godzilla" and "no" for "necklace" pronounced one after another quickly? Like "Gonome"?

It's worth noting (preferably in the answer) that Night Mode is there for a reason: to limit your exposure to both bright and blue light from the screen, both of which are thought to cause sleeping problems. Sure, disabling it is an option, but people should be made aware of the potential downsides of disabling it.

And it rests your eyes. Without wearing properly coated glasses it damages your eyes.
