When I don't really have much time to do my nails, I usually do split colour on them.
The colours I used are "Scented Bright Orange" by BYS (it doesn't smell though haha) and "Turquoise #3" by BK (some random Asian brand at Cosmetics Plus).
To achieve the look, I painted 2 coats of the orange and waited it to dry, then I did 1/3 of the nail in the blue. Then I finished off with a top coat. I like the look of contrasting colours so it's definitely something I love doing to my nails a fair bit :3
Also - sorry about the bad photo quality, took it on my phone!
