Cobalt Blue

Laying on her back in the sand Katara decides for the first time in her life that she has a favorite color. As she thinks about it she realizes it was her favorite all along.

After being alone with Zuko for a few months she developed the habit of speaking without a filter. She would say whatever was on her mind to make up for the amount of brooding he did. That's what their relationship was, hours of apology filled I love you's following brash fights and thoughtless insults.

"Zuko."

They'd made it to the beach in a day with the motorcycle.

"I think my favorite color is blue."

The sky was deep and dark as dusk approached.

"I've decided just now." She heard shuffling beside her as Zuko shifted through the sand from where he was standing by the water. The crashing of the ocean was rhythmic as she listened for Zuko's response.

"Hasn't it always been blue?" He fell to the ground next to her and dug his toes under the sand. They'd both taken the liberty of removing their shoes. Katara sat up. Her hair had been in a braid when they stopped, but once they got to the ocean and she jumped in the water she was pulling it down. She had stood ankle-deep until her legs were numb to the lapping and crashing; she mesmerized by the ceaseless blue.

"I suppose so." Zuko looked at her as she drew her legs up to her chest.

"I think that's mine as well." Katara glanced at him out of the corner of her eye.

"No it isn't." She snorted when he shook his head at her. When he let out a laugh she swiveled her entire body to look at him. Her expression turned from mocking laughter to completely serious. "I thought it was red." Zuko wrinkled his nose as he turned his body so that they were facing each other.

"It is definitely blue."

"You always used to wear red, and you had those dark red shoes that you wore all the time. You had a red back pack. Whenever you got to pick a color, you picked red!" Zuko laughed before reaching for her hand that was flying through the air with each new exclamation.

"Well, now I pick blue." A blush rose to her cheeks as she realized what he'd meant by his words. Her voice was flustered as she glanced at her trapped hand.

"Blue?"

"Always blue."

A/N: I know this chapter is really short.

I just wanted to keep it short and sweet because this prompt was leaving me feeling really uninspired... Not that it was a bad prompt I just had a day that made me feel particularly useless. I'm sorry, loves.
