Hi! I am choosing between these 2 grouts to go with my white subway tile. The Custom Platinum is lighter. Anyone have anything good or bad to say about either?

I am really open to both. My (former) designer had suggested the Platinum, but it looks very light, and I hear it gets even lighter after it drys. I like the subway tile work to be seen, as opposed to being one big sheet of white. But of course, I do not want it too dark....

Thanks.
