Just had a whole set of temporary teeth done before going to Florida. They are OM1 very white! Is there a glaze ?

Is there a glaze that can go over temporary teeth and then also porcelain fused to zirconium permanent teeth that doesn't darken the teeth? Don't want to go through this again. I feel the OM1 opaque look is just too white but I was told to go light and they can tone them down. But don't want a glaze that will make them grey.
