Celine Belt Bag Color Opinion

I am obsessed with the Celine Belt Bags and I have always thought I would purchase the Black or Light Taupe, however today when I went into the store I saw the Abyss Blue and it is just stunning! I am so torn, I tend to wear a lot of black regardless of season and tend to alternate between black and neutral colours. What colour should I get?

 

Thank you so much, had not considered the blue would change at all in the sun. You have sold it too me
