This little unicorn has light gray, violet and purple blue color. I’m going to draw Rarity alone. But I don’t like to use color pencils. I use only black pencil, because for me a color does not matter. But if you want to paint it, use my instructions without the last stage. In last step I do hatch, and you can paint her.
How to draw Rarity step by step
Step one. Create a sketch using the trunk circles.
Step Two. Add her mane and one eye. She stands sideways, only one is visible.
Step Three. Contours sharper.
Step Four. I add shading. You can follow my example or colorize Rarity.
