Rarity is a graceful white unicorn with a beautiful and stylish mane and tail of deep purple and rosy pink. Her proud cutie mark is a trio of delicate pink diamonds. She stands in a meadow of fresh flowers, with a loyal pet dog at her feet.
For this lovely coloring page, I would recommend adding a variety of colors to create depth and color contrast. The purple and pink hues of the mane and tail could be further emphasized with darker and brighter tones of purple and pink. To make the flowers stand out, select a few different shades of yellow, orange and pink for the petals and for the leaves, try incorporating hues of deep green. Furthermore, to add some sparkle to the diamonds on Rarity's cutie mark, I would fill them in with glittery gold or silver. Finally, your pet dog should be given a bold color, a lively orange-brown is a good choice!
