That was until I spied Made in Chelsea's Binky Felstead and supermodel Joan Smalls working a colour-flash lash!
It's not just a hot look but a clever flaw-fixer too. 'Coloured mascara livens up the eye area, making you look more awake in an instant,' explains Avon's ambassador and make-up artist to the stars Liz Pugh.
Coloured mascara: tried and tested
L'Oreal Paris Miss Manga Mascara in Turquoise, £8.99
Have you ever seen a mascara so pretty? This unusual aqua hue gives a 'wowza' effect while the flexible brush lets you catch every last lash. Especially gorge on blondes.
Rimmel London Kate Moss Idol Eyes Mascara in Eye Rock Amythest, £7.49
You know something's a trend when Mossy puts it in her make-up range! This deep purple gives a 'blink and you miss it' effect - perfect if you're not brave enough for super-brights.
Butter London Wink Mascara in Pistol Pink, £15
Pink's not the most wearable of shades but it's definitely high-impact! If you find it makes your eyes look sore, pair with a nude eye pencil in your waterline. For the last word in festival cool? Top off with full, dark brows.
Eylure Katy Perry Ka-Ching! Colour Pop Lashes, £6.45, eylure.com
Now this is a good way to test the trend! These falsies are surprisingly wearable with just the right amount of flutter. As you're not colouring your natural lashes, just layering on top of them, peepers stay looking defined too.
Miss Sporty Fabulous Lash Extreme Colour Mascara in Green, £2.99
A total bargain that still boasts an impressive colour pay-off. The shade of green's particularly vivid and looks stunning with hazel eyes.
Avon SuperShock Brights Mascara in Royal Shock, £8.50.
This electric blue buy is a good'un. The colour is one of the most opaque I've found while the chunky wand delivers va-va-volume.
Top tricks for pow! peepers
1. Choose the right hue for you. 'Purple mascara flatters green eyes while blue looks amazing with brown eyes. And blue eyes really pop with green mascara,' advises Liz.
2. Keep your lips nude. Always. This look is the beauty equivalent of sports luxe fashion - think minimalist with a dash of colour. Skip blush too and just sculpt your cheekbones with bronzer.
3. If your lashes are naturally dark, it can be trickier to nail totally opaque colour. The answer? Blank them out with white mascara first then layer your colour on top once dry. Try Kiko Building Base Coat Mascara, £7.20.
4. I've discovered one of the drawbacks to bright lashes is that they can make your eyes look less defined than you're used to. Fab fixes? 'Try wiggling a bit of black mascara right at the roots then brush your rainbow hue through the middle and tips to maintain definition,' says Liz. 'Or apply bright mascara all over then black to the outer corner lashes for a wearable, winged effect,' she explains.
