Color of my grout

[John_S]

I’m bad with colors. Trying to asses if my current grout color is white, ivory or light grey. I wanted clean the grout and use a grout pen to match existing color. The white seemed to be an incorrect match. What is your opinion on what the grout color is from this pic?

It looks like white. But the most important thing is you need to know the company name of the old grout
