You can edit the svg of course, the simplest solution.
I don't know which colorization you want. But other single color (!) changes are possible with combinations of invert/sepia/saturate/... css filters.
For example add to your additional.css-template
Code:
.b-icon__like {
filter: invert(27%) sepia(51%) saturate(2878%) hue-rotate(346deg) brightness(104%) contrast(97%);
}
There are some filter tools online to improve this combination.
