If that's an aesthetic question, Isaac, I'd wanna get the opinion of whomever made the grout color selection.
In general it would be a flexible sealant meeting the applicable requirements of ASTM C920 for the application or one of the pre-fabricated strips available from a number of manufacturers for the application.
We'd need to know more about the installation to get any more specific, I think.
My opinion; worth price charged.
