Hi Lilibel03
There are tons of color-shifting paints. House of Kolor makes what is considered to be the highest quality stuff, but it’s hundreds of dollars for a few ounces.
maxmercy used some on his longboard in this thread, and it was the 1.29 / bottle variety from a crafts store:

You can also buy inexpensive color-shifting paints in rattle can kits. The company is called DupliColor, and they sell these rattle-can kits at every auto-parts store on the planet (Auto Zone, Kragen, etc). A kit is about 18 bucks, and has 3 cans: 1 black base, 1 color-shift, 1 clear coat.
I doubt they are the same quality and effect of House of Kolor, but if you just want to dip your toe in the water, it seems a low-risk option. Here’s the website:

Another inexpensive way to go is to just buy a rattle-can base black (or black for your spray gun if you’re not afraid of compressed air like me), and then mix a clear gesso with this kind of thing:
This company sells all kinds of color-shifting paints very inexpensively. maxmercy mentioned them in this post above, but their site is:

When I grow up and am no longer afraid of compressed air, I’m going to try the $50 bucks worth of paints I bought from them and let you know how they turn out
Good luck, hope that helps!
