Which color is better, wall painting, acrylic paint or poster? What pen should I use?

It must be acrylic pigment. Waterproof after drying, with better performance. Advertising paint is easy to get wet, dry or change color after drying. As long as your foundation is ok, acrylic pigments are generally easier to store for a long time and the price is more expensive than advertising paints.

Acrylic pigment is not easy to wash off with water. If your base is porcelain or glass, you can wipe it with hot water or hang it with a knife, but it needs to be smooth. If it is made of cement or paint, it is not easy to get rid of it.

The use of these two pigments is basically the same, with or without water. You can use any pen for both pigments, depending on what effect you want. But if you use acrylic pigments, you should pay attention. After painting, you should wash the pens before they dry, otherwise it will be difficult to get them off. You can buy acrylic pigments from Taobao. If you sell less painting materials there, you can check the price of Taobao, about 16 cans.
