Step 2: Add the Dots
Now that your nails are prepped, you're ready to start painting. (The polishes here were created using the new Olive & June x Zeba Collection.) For the rainbow dot nail tutorial, select four or five colors, depending on how long your nails are, to create a gradient effect. You can use a Q-tip, bobby pin, or a nail-art tool to apply the dots — Tuttle recommended dipping the back end of the Clean Up Brush ($8) into each color. Once you finish adding a dot of the first color onto each nail, repeat with the remaining shades.
"The beauty of this look is you can mix and match shades to make it your own," Noor said. "Color has power and for me, these vibrant shades are super uplifting and playful."
