What is the function and effect of transparent pigments or transparent glues in oil paints?

The effect of transparent paint is to make the dark part of the picture.

It is very transparent, not very dark and dead, and the bright side of the painting will appear particularly translucent, spiritual, and more suitable for highlight. In general, transparent pigments are suitable for realistic oil paintings.

Oil painting pigments are divided into two categories: mineral and chemical synthesis. The original pigments were mostly mineral pigments, which were ground by hand into fine powders and only used to reconcile epistaxis when painting.

Inside. In modern times, factories have been mass-produced and tin tubes have been filled, and the variety of pigments has been increasing. The properties of pigments are related to the chemical composition they contain, and when mixing colors, chemical reactions can cause adverse reactions between some pigments.

Therefore, mastering the properties of the pigment can help to get the most out of the painting technique and keep the color of the work unchanged over time.

Advertising paint is actually gouache paint, the synthetic material is the same, it is a kind of pigment that dissolves in water and has covering power.

Watercolor, on the other hand, dissolves in water but does not use covering power, and is much more transparent than gouache paint.

Acrylic paints. After the painting is dry, it will not dissolve in water, it will not be washed off, and it also has the ability to cover. Oil paintings, the performance is different, they are adjusted with oil, mainly using turpentine.

toning oils, varnishes, etc. Various oils have taken the place of water in gouache.

The oil painting is painted on canvas, linen. And it should be stapled to the painting socket (the orbit is generally wooden, with size and size, and can be customized by yourself). Put the cloth with milky glue.

Scrape a few times. (Each time you apply it, wait for this layer to dry and then apply the second layer), and apply it several times with the base material after drying. Wait to plug the gap in the cloth. Then flatten with sandpaper. before you can paint.

Oil painting has its own oil paintbrush, oil painting shovel and other tools. The pen should not be washed with water, because the painting should be done with the help of oil, so the "shabu-shabu" should be prepared with soft paper to wipe off the color that is not used, and then wipe it clean with turpentine. You can also brush it with soap and rinse it with water.

In oil painting, black is a very common color. (Use a color palette, preferably wooden.) Glass is fine, and so is plastic. ）

Last year, I took a class on oil painting techniques, so I'll give you a rough analysis. As far as I know, there may not be any transparent pigments produced in China at present, and generally we use foreign ones, about thirty or forty yuan (small branches), Germany, and Australia. You can buy a large one for a dozen dollars in China, and its transparency is very poor.

It is said that a lot of additives are added to it to make it so cheap. This also results in poor coverage of some pigments. I tried a certain brand of white in China, no matter how white you add it, the white just can't light up.

Foreign transparent pigments are divided into translucent and transparent, and it seems that transparent ones are more expensive. When painting oil paintings, you only need to use a little bit to dye a large piece, there are few additives, the highest grade of transparent pigments are almost non-additive, there is a blue color is taken from precious gemstones, the color is very pure and beautiful, and the price is super expensive. The effect of transparent paint painting is to make the dark part of the picture very transparent, not very dark and dead, and the bright side of the painting will appear particularly translucent, spiritual, and more suitable for highlight.

In general, transparent pigments are suitable for realistic oil paintings.

Depending on the choice of raw materials you choose, oil paints are divided into two categories: transparent and opaque.

Transparent pigment refers to a certain toner that produces a transmission effect after mixing with oil to make the color layer transparent, and the transparent color has the characteristics of saturated hue and poor coverage. Opaque color (or pink color) refers to the reflection effect of toner and oil mixture, which makes the color layer in an opaque state, and the opaque color has the characteristics of real hue and strong coverage. Transparent colors generally include deep red, emerald green, plain blue, ultramarine, dark brown, violet, ivory black, etc.

Opaque colors generally include white, earth yellow, earth red, pink green, medium yellow, lemon yellow, bright red, vermilion, lake blue, cobalt basket, etc. There is also a difference in the strength of dyeing ability in pigments, which is caused by the different degrees of absorption of various pigments by other materials, and we can feel that various pigments have different strong and weak influences in color mixing, such as deep red, plain blue, emerald green, etc. In painting and color grading, the pigment with weak dyeing power always makes you feel that you are not working hard in the application, and the pigment with too strong dyeing power has to make you want to suppress it at any time.

Therefore, we can try our best to choose some pigments with moderate dyeing power to play a mediating role, so that the pigments are easy to mix in the blending and are beneficial to grasp the proportion of color purity. Generally speaking, white, earthy yellow, earthy red, pink green and other powdery pigments are easy to blend intermediate colors.
