[FR] Let user pick from a list of predefined colors for selection and cursor colors.

[MayurSMahajan]

Description

Right now in the Settings, we let the user pick a hex color for the selection and cursor color options.
Non-technical users might not be familiar or comfortable with using direct hex colors.
So we should append a list of some 6-7 common colors as we have in every other color picker menu.

The Hex color option should not be removed, it offers amazing customizability.

Impact

Users who are not familiar with Hex code coloring will also have an option

Additional Context

We can implement color pickers from packages:
