Typically found in 1d4 pots inside a fine wooden box with a brush (weighing 1 pound in total), these pigments allow you to create three-dimensional objects by painting them in two dimensions. The paint flows from the brush to form the desired object as you concentrate on its image.
Each pot of paint is sufficient to cover 1,000 square feet of a surface, which lets you create inanimate objects or terrain features--such as a door, a pit, flowers, trees, cells, rooms, or weapons-- that are up to 10,000 cubic feet. It takes 10 minutes to cover 100 square feet.
When you complete the painting, the object or terrain feature depicted becomes a real, nonmagical object. Thus, painting a door on a wall creates an actual door that can be opened to whatever is beyond. Painting a pit on a floor creates a real pit, and its depth counts against the total area of objects you create.
Nothing created by the pigments can have a value greater than 25 gp. If you paint an object of greater value (such as a diamond or a pile of gold), the object looks authentic, but close inspection reveals it is made from paste, bone, or some other worthless material.
If you paint a form of energy such as fire or lightning, the energy appears but dissipates as soon as you complete the painting, doing no harm to anything.

What would happen if you painted a door or window on a dragon
DRAGON DUNGEON! DRAGON DUNGEON! DRAGON DUNGEON!
Instant house-ruling when my party got this from a hoard at lvl 7: The paint can not create valuable metals/earths/gems, life or chemicals. Otherwise you have mayhem in your campaign. It is a fun item, but the way the rules are written the interpretation of what is possible is wide open....
So...Sane Prices Guide pdf has this at 200 gp...WAAAAY too low IMO.
You can find the guide here:

Why is 200 gp too low?
Rapiers sell for 25gp, and you can create rapiers with these. Lots, and Lots of rapiers. :-)
You can easily paint 2 rapiers in a 1' x 4' area, which is 2 per 4 square feet, or 2 square feet per rapier, or 500 per pot, or 2000 rapiers for a full set of 4 pots. The 2D space is the constraint, not the 3D volume. Volume wise, you can craft many thousands of rapiers given how thin they are.
2000 rapiers * 25 gp = 50,000 gp.
Granted, it would take you a LONG time to paint them and a LONG time to sell them, but this is very rare for a reason. 200 gp is a joke and at least two orders of magnitude too low.
In my game these sell for 25,000 gp. YMMV.

You could potentially gain the ability to see it’s internal organs if a window, a door can only go as far as it is thick, so a door wouldn’t do much except you could get through the scales to potentially decrease the AC.
I wonder if this thing also mimics the weight of the object? like if you us eit to make a key, or use to copy a totem that's trapped by a pressure plate. could you pull an Indiana jones type thing. would the object mimic that hardness? like if you make a key, would it be strong enough to open a lock. Also it doesnt say that you cant make organic material...so what if you draw a feast that costs less than 25 gold...and then charge like 5 gold per person.
How does 2d objects turn into 3D objects in the first place?
Ever seen a Zach King video?
Except you've now crashed the market and adamantly is now worth the same as copper.
Wait, so hear me out...
You're in space, and you throw a tiny pebble towards Earth. You use the pebble as a surface to make a very, very large rock. It'd still be going at the speed you threw the pebble at, since it's tied to the surface's own position/velocity. Now you have a MASSIVE meteor hurtling through space towards Earth going as fast as it would have been going if you had just thrown it as a pebble, because, well, you really *had* just thrown it as a pebble. Assuming your character's strong, that meteor would be going pretty fast, and would be pretty large...
