I love this color! I usually stick to reds and pinks, but this is a great, vibrant blue. It's a little sheer, so I generally have to put on a few coats.

Blue my Mind is from the original OPI Brights collection released in 2005.

It is a bright royal blue with a metallic sheen. It is true blue (no green undertones), very glossy looking and in the sun this colour just glows!

I bought this colour at the airport en route to a tropical holiday destination, My case already contained about 7 bottles of OPI and when I saw how vibrant this blue was, gleaming away on the OPI stand....I just had to have it!

The colour looks great on fingers and toes, especially with a tan.
It compliments denims, any nautical colour themed outfits and I also think it looks great with bright yellows and other citrus colours as a contrast (love this on my toes when I wear my bright orange Jimmy Choo sandals).

I also think this colour is great for making a patriotic statement (red/ white/ blue)

I also have OPI Swimsuit Nailed which I thought may be a bit similar, but they are very different - SNI is a foil with a leaning to turquoise..this is royal blue - so worth having both.
This colour is also a good base for various glitters to get different effects e.g.
OPI Absolutely Alice - for a full on blue look
OPI Rainbow connection - something more colourful...

Application is smooth and easy, but as with a lot of bright/dark colours, you need a steady hand, as mistakes really show up.

You can get away with 2 coats for this polish, but for an absolutely perfect finish that looks like blue satin - I use 3.

Does it stain the nails? - NO! Extra points for this as many blues do.

I love this colour. It is great for all year around and one of my favourite blues.
I would score this 5 and would buy it again, unless OPI make a similar one with a more exciting name.

This polish is pretty sheer. It takes 3 coats for the best effect.
That is my only complaint.
I love love LOVE this color! It's so shimmery and electric! The formula's good, too. Solid nail polish. Spices of my normal neutral polish collection.

Beautiful, rich royal blue with shimmer, for me opaque after two coats. Perfect for a Memorial day or 4th of July pedicure :). Dries very quickly with no streaks and application is smooth and even. Looks gorgeous next to my fair, (slightly tanned) skin.

This is one of my favorite polishes in my whole collection. I'm a sucker for midnight blues, its probably my favorite color. I saw this beautiful shimmery midnight blue color at my local drugstore and just had to buy it. Its opaque after three coats and has a beautiful sparkling finish. I love to use this with OPI Gold Shatter on the top to make my nails look like a starry sky.

It's most beautiful indigo ever, It's verry long lasting, 3 coats are enogugh for a long lasting color, it amaaaazing

The shade is amazing. I am not a fan of dark nail polish but this is just gorgeous. It looks great against my olive complexion. First coat is terrible, but the second coat goes on opaque. I love it, but if I could change one thing, I would make it a little more on the Cobalt blue side as oppose to navy.

I love love love this color!! I just bought it and couldn't wait to put it on. It's a shimmery blue. I have a bit of a collection of OPI colors...this one is my new favorite. I have fair skin with a pinkish tone on my toes. I don't tan at all. I think it looks great on my toes. I think it would be a little too shocking on my fingers...but maybe one day I'll feel adventurous enough to try it! Until then, I can't stop admiring my toes! : )

Blue my mind is a magnificent royal blue with lots of shimmer. It was one of my first OPI polishes and I keep coming back to it time and time again. I've had so many compliments on this colour. It does need two to three coats to become as opaque as I like but I knocks my socks off every time I apply it. I currently have it paired with some black shatter and it looks absolutely phenomenal.

I love the colour so much. It's a brilliant deep royal blue and looks lovely in contrast with my pale skin. The first coat is sheer as others have said, but it only took me two coats on top of a base coat to get the colour of the bottle. I'm giving it only four stars because the formula dried out pretty quickly. I always make sure my nail polishes are completely shut, but for some reason this one got thick and goopy within only a year. Would buy again, hopefully I'll have better luck in that department.
