This year's biggest nail trends fall into two general categories: colour overload or barely-there neutrals. With the latter, you've got the sheer-beige "supermodel" nails trend, whereas "coquette" nails are all about hyper-feminine, over-the-top embellishments and designs.. Now, there's a new and emerging design taking front and centre for summer: watercolor nails trend. Like a watercolor painting, the options for this nail-art design are truly limitless — the only condition is that you incorporate multiple colours.

When you paint with watercolors, the different pigments are slightly translucent (thanks to the addition of the water) and blur together; watercolor nails have the same effect. You can opt for a rainbow motif, combining a large range of colours, or stick to a theme with different shades of the same pigments.

That's what celebrity manicurist Kim Truong did for her client when they requested a watercolor manicure and showed an image with charms for reference. "We customised it to her own liking by adding more of her favourite colour, purple, and opted for no charms," Truong tells POPSUGAR. The look is not too far off from marble nails, or even the viral "aura" nail trend that has been a popular choice of late.

While this manicure probably looks like something only a professional can do, Truong explains there are ways to do it at home. At a salon, "These nails were created using an actual airbrush machine to blend the various colours together seamlessly," she says. But if you're looking for a DIY version, "You can recreate this look at home by using regular polish and a makeup sponge to dab and blend the colours together." The key is to use a light hand to get that airy, harmonized finish.

If you consider yourself to be a maximalist and the colours alone in this manicure aren't enough, you can incorporate things like 3D charms, glitter, and even a glazed finish.
