Step 1: Paint your nails with the white base colour. Allow to dry.

Step 2: Using your red striper, draw a large square outline on the left side of the nail, that takes up about a third of the nail area. Fill in the square with red.

Step 3: Take your blue striper and create a smaller blue triangular shape at the bottom of the nail that just touches the red square. Fill in with blue. Use your yellow striper to create a small yellow triangle at the tip of the nail, not quite touching the red square, and fill in with yellow.

Step 4: Once the colours are dry, use your black nail-art pen to draw straight lines between the red, yellow and blue shapes, so that they are all outined.

Step 5: To finish, add a small black outline under the yellow triangle and two small vertical lines under the red square.
