Everybody on their whole planet does it so they're used to it. Healing would be orange and combat would be grey and so on though.

Well as long as they don't go about imposing it on other people they can check the job listings and see if an employer will sponsor them for free tuition. Magic is useful.

They peer at listings.

Magic usually can't be picked up at all if you have a hard time doing accounting or scanning a scientific paper to figure out how misleading the news coverage is.

There are lots of listings to make magic artifacts on a commission basis; the ad lists the price they retail at and the cut the company takes until it has been reimbursed for tuition and then some; they take a week or so to make each for people just starting out.

People interested in magic research jobs are encouraged to take the standard classes and impress their teachers a lot and then get a scholarship for higher-level coursework.

There are healing and security jobs. Most of them pay for the lessons in exchange for a cut of your subsequent salary. The security ones require extensive screening.

Some of these people would like to try it out.

There are applications! Some of them want you to do a intelligence test that predicts whether you'll be able to pick up magic. 

Some of them pass and some do not.

The ones who pass can get sponsored to start at magic school once the new term starts.

Peka gets a little shimmering handwoven tapestry of Katin and another note. The note says 'I made you and Katin impossible to seriously injure. I actually did that first but it's not easy to test and seemed like it might be hard to believe. The most notable effect if you stay away from stray bullets is that you can go without sleep and food. Tapa would probably be displeased if you used this to go around touching all the things but I don't, personally, mind if you do.'

...she doesn't go around touching things. She visits her baby when she doesn't need to be at work.

He queries Rebecca about her favorite foods.

"Chocolate. And the house elves make these awesome pork medallions but I'm not sure what's on them."

Does Peka like those too?

Yes!

Uncannily good food recommendations! More beads with minor magic music!

She sings bead songs.

The magic works that way, too.

Oooooooh.

(Army uniform that looks just like hers but is made out of something very expensive and possibly magic, is wonderfully comfortable, and always has a different exotic chocolate in the pocket! Baby toys for Katin, magical and hand-carved and so well-chosen it's as if he asked several other Katins what their favorite baby toys were! Little unexplained potion in a flask!)

Well heck she'll drink it and see what happens.

Lets her breastfeed Katin, apparently.

Eeeee!

The next time she returns to her tent it is sized and furnished like a upscale studio apartment. It has a hot tub.

...she gets out and circles the tent. Yep, still a tent on the outside.

Totally unremarkable and tent-sized!
