For those people who want to
learn painting, no matter what type of painting they choose, they may need to grasp some basic theories and skills about painting. Learn to deal with various colors is important too.
Different
pigments have different covering properties. Some are extremely transparent, barely showing on top of another color. Others are extremely opaque, hiding what's beneath. Considering this, and not just what the color is, can enhance a subject. For example, using a transparent blue in a sky gives a greater feeling of airiness than an opaque blue will. But how to test whether a paint color is opaque or transparent?

Things you will need
Drawing a special chart will enable you to get the result quickly and correctly. All the things you will need include the colors you usually paint with, one medium-size brush, a piece of cloth, jar of clean water, a pen and a piece of white people.
How to Make a Chart
First you will need to sort out your colors in an order that makes sense to you, then mix up a little of each color, paint a vertical stripe of each and wait for them to dry. In the same order, paint horizontal stripes for all the colors. If you're using a ruler, wipe the edge after each stripe so you don't contaminate the next one. Remember to record the names of the colors next to each stripe.
Check the Results
Opaque pigments are dense and tend to block out other colors. This makes them ideal for subjects that are solid and heavy, such as tree trunks.
Transparent pigments are light and airy, barely showing on top of other colors. This makes them ideal for atmospheric subjects such as a misty morning or diaphanous fabrics.
Semi-transparent are somewhere between the two. With time, you won't have to refer to the chart, but will instinctively know the properties of a particular color.
