if the icon is a built in icon from bubble you can use a condition to change the icons color on hover or if active
if it is a manual icon you can either set it up as an option set (use svg files) or a reuseable element and add params to adjust the color properties. or if it is an image then a reuseable element that switches the image based on property would also work (although svg would be best).
there are also animated icons available from sources like lordicon
you can make them animate on hover for example
