Unlike other types of paintings the watercolour is a painting technique that is assumed to be quite easy.

But in reality it is quite demanding. The brushstrokes must be fluid in order to make a high quality watercolour painting and they must be determined and precise because the colours dry quickly and tend to mix together creating certain effects which, if undesired, are very difficult to correct. In fact it is not possible to carry out corrections by overlapping colours on the painting as you would do with other techniques: each brush stroke is definite. The colours (pigments combined with natural Arabic gum) are obtained by diluting them in water. The material used for these types of paintings is paper, one with a high percentage of pure cotton since this material does not excessively deform when it comes in contact with water.
