Does the veil always have to perfectly match the dress?

I know that this question has probably been asked in multiple different ways, but does the veil always have to perfectly match the dress? I am only asking because some of the dresses I am considering aren’t the traditional ivory/white color. Some are more on the pale blue or lilac side. I’ve seen photos of brides wearing similar color gowns with a white veil and I don’t mind the look. I know I could possibly look into having a veil custom made usually a similar shade as the actual gown, but I am prepared for a Plan B (white/ivory veil) or Plan C (wearing a tiara or other headpiece instead of a veil). What do you ladies think about this? I suppose it’s ultimately up to the bride since every wedding look is so individualized, but I thought I’d get some outside input. Thanks! 😊
