If not, don't worry. Our team has been tracking the web's finest nail artists, and we've worked out 2017's hottest trend. This year is going to be all about rainbow nails. Colours are back, and back in a big way. Here are a few of the ways you can work them into your beauty routine.

Colourful manicures featuring geometric shapes are proving to be one of 2017's most striking nail art trends. Using tones like dusty teal and ballet pink, creative beauty fans have been creating looks incorporating cross-hatched lines, horizontal stripes and triangles.

Savvy nail artists are exploring how intricate but simple lines can accentuate their hands, and are coming up with some impressive results. When done well, these clever designs harmonise superbly with colourful summer dresses. It's easy to imagine them being combined with complementary make-up and clothing featuring similar patterns, conjuring up looks that go deeper than a first glance.

But it's not all about geometry in the world of rainbow nails: Pastels are also making a big comeback this summer. These gentle tones always seem to be in vogue for T-shirts, dresses and other clothing but they've been strangely neglected by nail artists for far too long. Thankfully, as the rainbow comes into fashion, that's all changing.

Talented beauty fans are discovering how vibrant pastel manicures can be. With the right tones of pastel blocks, artists can accentuate the depth of their skin tone, and also add a variety of attractive colours to their overall look. They can be a great way to turn seemingly bland outfits into eye-catching and original ensembles, and also work superbly with the pastel garments that everyone seems to have hidden away in their wardrobes.

There are plenty of other striking manicure trends in 2017. For example, using fine borders around colour blocks to accent nail designs is another popular option at the moment. It takes a little skill to ensure an even, slender boundary around the whole edge of the nail, but these designs create a really unique look.

If you've taken the trouble to come up with a neat design, the border acts as a "frame", underlining the design, just like frames do for pictures in a gallery. That way, your hard work will have the setting it deserves. Along with borders, we're also loving stripes and spots. There are some gorgeous looks featuring vertical stripes.

These motifs fit in nicely with the positivity of the season, reflecting the desire of nail artists to experiment and get their creations out in the open - something we can totally get behind. If that sounds like you: good luck, and enjoy 2017's rainbow nails trends.
