Child painted fingernails are the best. They tend to pick lots of colors!

The best way I've found to manage other people's pronouns is to use my own.

"Hi! I'm tanglisha. My pronouns are she/her."

Practice until it sounds natural. Include your pronouns everywhere that makes sense, I have them in my work email signature and zoom account. The other person will usually reciprocate if you're in person, even if they've never introduced themself that way before. A bonus is that it normalizes this as a way to present oneself. We shouldn't put all of the burden of managing pronouns on the minority who already have a hard time with them.

It's true that this might draw some attention, but the worst I've ever gotten was someone asking me why I refer to my partner as "my partner" when he's of opposite sex. YMMV based on where you are and the folks around you, I'm on the west coast but have coworkers all around the world.
