Mine is an H (non-certified).
However I like the color of the solitaire that I got for my anniversary (certified F) much better.
I have certified (I am talking AGS certification here) H color earrings that are ideal cut and they are wonderful. However, I like my F color ring better than those.
I would never have noticed the difference if I hadn't gotten the F color and got used to wearing it. I thought the uncertified H was white until I got the F. I still do think its pretty. But I like the F better. You cannot see the difference from the top. You see it looking through the side. Looking at the F from the side is like looking through an ice cube. I personally enjoy this. I tend to look at my rings a lot and I have come to love that icy white.
I am always hearing--or rather, I used to alway hear when I was on Pricescope, that well cut diamonds of whatever color H, I, J, whatever-- faced up 'perfectly white' but that has not been my experience. I think that well-cut diamonds SPARKLE more and the sparkle looks attractive. I don't think that a great cut makes an I look like a G (much less like a D, E or F). I think it makes it look like a very pretty I, which you might be fine with for one of two reasons a) you never see it next to a well-cut higher color, so it looks white enough to you--an I is still a white diamond, after all or b) you like diamonds with more color, which some people do. Not everyone likes or wants icy white.
Just by the by--IRL no one has ever asked me what the color of any of my diamonds are and this is something I think few people care about, once you get off the internet. So I don't think this is worth obsessing about, not one bit.
sounds like it wasn't cut amazing. You shouldn't be able to see color from the top on an F.
