To change/set the colour of a circle (or any standard SFML shape), use: setFillColor(sf::Color)

To animate the colour, change the colour depending on the time given by a clock (you can use sf::Time and sf::Clock (https://www.sfml-dev.org/tutorials/2.4/system-time.php)).

For a small example of animating values smoothly depending on time, you can take a look at this animation of the SFML logo (https://github.com/Hapaxia/SfmlLogoAnimation).
In particular, you might find most use of this section of code (https://github.com/Hapaxia/SfmlLogoAnimation/blob/master/SfmlLogoAnimation/SfmlLogoAnimation.cpp#L220-L229).
