I want to keep left click function fixed to color pick tool. Can it be done in paint.net 

I mean I always want to pick color  with right click. I donot want to click color pick tool again and again to copy colors.

Can it be done in paint.net

On my computer, left click is already for the color picker function.

 

There is a list of functions found here:

If you look under Settings (the gear wheel icon) you can change what happens after you click the color picker: 'Do not switch tool', 'switch to previous tool' or 'switch to pencil'.

I hope that is what you meant?

 

When using the color picker on an image a left click sets the primary color and a right click set the secondary.
However this does not apply to the palette color wheel... which personally I find annoying and irrational?... I expect there is good reason though!😉

What you want is not possible.
You can use the keyboard shortcut K and have
Color Picker set to Switch to previous tool.

I agree.

If so, I'd like to know that reason.
