I like it and would not change a thing. When tile colors differ, grout will be more visible with some colors. Given the cloudy nature of the picture (lower resolution? cloudy surround glass?) it is hard to see what to dislike about your grout choice.

The color block pattern is attractive and different. Definitely better than the row of accent tile circling the shower 2/3 of the way up the wall. I like how your design ties the white wall trim and white shower pan color into the design of the color blocks. If only the design had given the plumber the right height in order to center the shower control in its color block! That would have been perfect.

It is what it is! Not worth spending money trying to change this and possibly creating a bigger issue.

There is nothing to do but live with it until you decide to replace

I agree leave it now until you just hate it later and who knows maybe it will grow on you.

The shower glass looks cloudy and the white-white fixtures do clash with the various shades of tile.
Save up the money and redo it in a couple of years. I would suggest a vanity cabinet with storage space unless you have storage which is not shown in the pictures.
