To say that Hermione Lupin loved to draw would be an understatement. She drew everything, from people she loved to things she hated. It became more habit than anything else, whether it was all in her head, or she was using one of her many sketchbooks, or even a limb, be it her own or whomever happened to be sitting near her.
That is how Draco Malfoy's arm ended up covered in sparkly purple things.
Hermione hoarded pens, especially gel pens, and especially purple, so the probability that she would end up holding a purple one when she grabbed a pen at random was pretty good on any given day. Today in particular they had been paired up in potions and she, having memorized the textbook, had no need of a review. So, she was bored and annoyed (Malfoy kept his arm firmly planted in her personal space) a dangerous combination for anyone in her immediate vicinity, but seeing as the one person in her immediate vicinity was the cause of her annoyance…
Knowing Snape was a Legillimens, she sent a picture of what she wanted to do in his general direction, along with the loud banging of a gong, and watched.
The professor flinched and glared at her with a loud mental NO.
Hermione raised her chin in that same defiant manner and they glared at each other from across the room. In his head, she started wailing You Are My Sunshine as loudly as she could.
FINE DAMMIT!
Graçias sénior. Relax, I'm not going to hurt him!
He gave her a good scowl before starting off in the opposite direction, ignoring her. She, happy as could be, pulled one of her pens out of her hair and used it to cast a quick confundus on him, a notice-me-not on both of them, and rolled up his sleeve, eyeing his bony arm to find the best place to start.
After a few moments, she decided on the place Remus had told her that the Dark Mark could be found and wrote—in a very good forgery of his own writing, "Purebloods are sporks" and surrounded it with little hearts and flowers and winky faces just to bother him. Then, she took his hand and colored his second and third fingers completely purple. After that, she leaned him forward and wrote "All hail Drakey-poo" on the back of his neck, gave him a sparkly purple mustache, charmed his hair purple, and made it look like he'd fallen asleep on his desk, pulling his textbook in front of herself to make it look like she was reading it.
When she lifted the confundus charm, she kept the notice-me-not for a bit just in case. When he woke up he didn't look at his arms, so she figured she could lift the spell.

Draco didn't find out about her doodles until later that evening when Peeves the Poltergeist followed him into the Great Hall announcing the "great fakiness of his Drakinness' hair" among other, more offensive things while cackling and poking him repeatedly in the back of the head.
The consequent scream of "LUUUUUPIIIIIIIIIINNNNNN!" gave her sweet, only slightly morbid dreams for many nights to come.
