Solid objects are seen within characterized limits. These breaking points are called form lines. The form is the thing that characterizes the shape, or frame. A surface can have numerous structures. Structures are characterized by their forms, which can be straight or bent. On the off chance that the visual change is gradated or has little subtleties in shade or tone, it is hard to characterize the frame. Geometric structures depend on scientific actualities on focuses, lines, surfaces, and solids. Natural structures are made by living creatures or are based on living life forms. Arbitrary structures are made through proliferation, oblivious human activity, or accidental impact from nature. There are a set of structures which serve as fundamental symbols in Western ideography. They are the essential signs man has made as total decipherable elements.
Hues are diverse wavelengths of light. Solid items and the materials of which they are made reflect just piece of the light range and thusly show up as though they have shading. Tint alludes to the wavelength of the shading and is discrete from its power or immersion. Immersed tones are those we are familiar with finding in the chromatic circle. Black, grey, and white are hues without tint. Tone portrays a shading's softness/murkiness. The tone, additionally called the shade, is the shading's substance of dark. Saturation depicts the relative proportion of the shading's tone and white substance. A shading with little saturation contains a lot of white, for example, pastel colors.. A structure is solid when its structure lines are obvious or effectively impact the type of the items in the structure. Solid structures are visual organizations in themselves. An unmistakable structure is a structure with noticeable structure lines. A structure is dynamic when the structure lines impact the type of the items in the structure. A structure need not be visible to be dynamic. For example, the grids used within print and web design are invisible to the viewer’s eye, but serve great purpose in the organization of compositions.
A texture is a structure that can be seen as well as felt. The texture can comprise of structure lines and additionally protests. Texture exists in materials and can be made through engraving and application. Texture can be organic (wood bark, smooth moss, fuzzy leaves) or manmade (velvet, Braille texts) Textures can have an elaborate, arbitrary, or mechanical outline. The arrangement of textures is equivalent with respect to structures: formal, casual, radiation, and winding.

The composition of this photo is really interesting- I don't think these mushrooms grow this close in relation to one another. The photographer would have interlaid them before snapping this photo. The fuzzy rinds of the mushrooms, and the radial ridges that curve towards the base of the mushroom are almost eerie to look at.

This range of colors (in man-dyed wool) shows the color scale, with saturation based on addition of black or white (or in this case, how much dye is added to a white-colored wool.)

According to the architects, "Cohesion was also an issue in the configuration of the property, because the widths of the facades are based on those of the typical canal houses in Amsterdam. Baumschlager Eberle have kept to architectural tradition in the Netherlands in their choice of colours for the dark concrete facade and the contrasting window frames (green and beige)."

The deep, rich colors of the soft silk, the veined leather, coarse wool, and soft velvet contribute to their sensory effect. The photographer was very careful to use light to their advantage, to add contrast and highlight the textures. We can imagine what these textures feel like under our fingertips, without even touching them.
