Istikhara

I am seeking istikhara interpretation which I did for marriage. I was shown photos of 2 girls. One was wearing pink clothes and the other blue and was introduced to us by my brothers wife. In the dream I saw it was dark and my brother is saying I should get married to that girl who was wearing blue clothes in photo. Then I saw her laughing and happy and then she looked towards me and said Blue color suits you and I saw myself sitting there wearing a blue t-shirt. I am confused now whether she is a good match for me as some people say blue color in a dream represents depression and calamity and seeing someone laughing is not a good sign. Please guide me.
