A principle refers to the fundamental aspects or rules of something.In the visual arts, it would refer to its fundamentals or rules. A set of rules that artists follow that informs the composition? Often, these are also criteria used to analyze artworks.
There are three primary aspects or elements related to color, namely, hue, value, and intensity (this is also sometimes referred to as saturation or chroma).
Form as an art element refers to the three-dimensionality of an object, it is usually described as having volume, which comprises width, height, and depth.
Shape relates closely to form, but the main difference is that a shape refers to two-dimensionality. It is often described as “flat”, with only length and width.
Space is often described as the “distance” either “within”, “around”, or “between” the compositional space, which can be a canvas, a sculptural space, or any other form of art.
Texture is all about feeling, and there are typically two primary ways it is conveyed in visual art: in real life, or three-dimensional space, or through illusion.
Balance is about the compositional “weight of visual elements”, whether these are applied in such a manner that provides the effect of even distribution.
Proportion refers to how an object’s parts in a composition relate to each other due to their size or shape. This will either create emphasis or different visual effects.
