(Thank you, Saj te Gyuhyall!)
Barry was trying his best to keep the pencil still over the sheet of computer paper, but Wally kept bumping his elbow. The ten-year-old was fidgeting in place and excitedly rambling off instructions as he peered over Barry's shoulder at the sketch in progress.
"I want that part to be yellow, and the pants red, and…black lightning bolts for the belt!" Wally happily pointed at parts of the sketch while Barry used his speed to keep up with the suggestions. Hal was across the table drawing up some designs of his own, and his head snapped up suddenly, eyebrows drawn together in abrupt concern.
"No yellow!" he grumbled.
Wally and Barry looked up at him with raised eyebrows. Barry finished darkening the black lightning bolts around the waist of the Kid Flash costume they were developing. He pretended like he was having trouble hearing and cupped a hand around his ear, "Mostly yellow? Is that what you said? Oh, that's a great idea."
Wally looked a little confused, but Hal shot them an annoyed scowl and sighed, "Fine. Just don't be all surprised when one of you falls off of something, and I can't catch you because you've decided to make an unacceptable percentage of your uniforms yellow."
"He's gonna be Kid Flash," Barry set the pencil down and slid the design over to Wally for inspection. "At least some part of his costume has to be yellow. We're going for complimentary colors here."
"Then why not orange?" Hal proposed. "That goes with red."
Barry wrinkled his nose, looking over at Wally and his bright red hair, "I think that would clash really badly with the red hair."
"Then make the cowl cover his hair up," Hal handed over a sketch of his own that was mostly stick figures and boxy gear with lightning bolts scribbled all over it.
"No!" Wally set down the paper with a frown. "I want to see my hair. Dad says his mask gets really hot sometimes."
"It's better identity protection if people can only see your jaw," Hal offered with a shrug. Barry really wanted to point out that Hal's green domino mask was one of the smallest masks out there, but he kept quiet and just smiled.
Wally looked at Hal very seriously and said, "No."
Barry laughed, working on the lightning bolt earpieces that would go on either side of Wally's mask. They'd been arguing over the design of this costume for hours now, and he didn't think they'd ever get done with it. Hal flicked part of an eraser at Wally and snickered when it hit him right in the nose. Two seconds later, all the papers spread over the table were in the air, and Wally was drawing on his pop's face with a marker at superspeed in retaliation.
