Azula is cool, calculating, clever. Absolutely everything about her is perfectly planned out, purposefully executed, one hundred percent effective. She goes for clean, intimidating, sharp. She stands before the kneeling servant, closely scrutinizing the different shades held out to her.
Red
More specifically; rouge, sunset red, velvet red, pale red, deep red, maroon red, blood red, poppy red, red-orange, copper red, fire red, and flushed red.
Pink
More specifically; pale pink, heated pink, rose pink, cherry blossom pink, blush, salmon-carp pink, dull kingfisher pink, bitten pink, and pearl pink.
The Princess considers the various shades and colors, carefully judging each one's effectiveness, before choosing the one.
She picks up the tube and approaches the mirror, uncapping it and applying it cleanly across her lips.
She curls a closed mouth smile at herself in satisfaction.
No one knows lipstick like Azula.
