Color spaces

Color is typically organized in a hierarchal fashion, based on how colors are mixed. A color space helps to define how the colors are mixed, based on the medium in which the colors are used. There are two different kinds of color spaces:

Subtractive: A subtractive color space is the traditional color space that most people refer to when they talk about color. It is pigment-based color, as in the mixing of paint. In a subtractive color space, the pigments manipulate the wavelengths that our eyes see.

Additive: An additive color space is an electronic color space. It is light-based color, as in the mixing of color on the computer. In an additive color space, light is added to the screen in differing amounts to produce color.

Texture

Active vocabulary

Texture is used to create surface appearance, and relates to the physical make-up of a given form. Texture often refers to the material that is made of, and can be created using any of the elements previously discussed. Texture is both a visual and a tactile phenomenon. Texture is defined as the surface characteristics of a material that can be experienced through the sense of touch or the illusion of touch.
Texture can be used to accent an area so that it becomes more dominant than another. In visual images, actual textures can be used, such as cloth, boxes, small objects, and natural items. Texture is the visual or tactile appearance of a surface. Surfaces can look or feel smooth, rough, soft, cool, or warm. They can look pleasant, which can have a dramatic effect on a display.Texture refers to the properties held and sensations caused by the external surface of objects received through the sense of touch. Texture is sometimes used to describe the feel of non-tactile sensations.

Texture can also be termed as a pattern that has been scaled down (especially in case of two dimensional non-tactile textures) where the individual elements that go on to make the pattern not distinguishable. Texture in a painting is the feel of the canvas based on the paint used and its method of application. There are two forms of texture in painting, visual and tactile. Because texture uses two different senses it is a unique element of art. There are 4 types of texture in art actual texture, simulated texture, abstract texture and invented texture.
