Wandering through the Walmart craft section can be a fun experience I came accross some acrylic paints in a huge variety of colors. The folkart line by Plaid all come in 2 oz bottles. The consistency of the paint is perfect right out of the bottle for painting card or formers and the colors are true and go on smooth with just a mediocre brush. I grabbed a few essential colors for starters like silver, bronze, copper, grey and black. For the price of 1.99 Canadian dollars a bottle it was well worth it and the results are great.
