Question

what are all the colors mixable in this world and what colors would it make?

Answer 1

Answer:

Color theory

In the visual arts, colour theory or color theory is a body of practical guidance to color mixing and the visual effects of a specific color combination. There are also definitions (or categories) of colors based on the colour wheel: primary colour, secondary colour, and tertiary colour. Although color theory principles first appeared in the writings of Leon Battista Alberti (c. 1435) and the notebooks of Leonardo da Vinci (c. 1490), a tradition of "coloury theory" began in the 18th century, initially within a partisan controversy over Isaac Newton's theory of color (Opticks, 1704) and the nature of primary colors. From there it developed as an independent artistic tradition with only superficial reference to colourimetry and vision science.[citation needed]

The foundations of pre-20th-century colour theory were built around "pure" or ideal colors, characterized by different sensory experiences rather than attributes of the physical world. This has led to a number of inaccuracies in traditional colour theory principles that are not always remedied in modern formulations.[citation needed]

Another issue has been the tendency to describe colour effects holistically or categorically, for example as a contrast between "yellow" and "blue" conceived as generic colors, when most color effects are due to contrasts on three relative attributes which define all colours:

Value (light vs. dark, or white vs. black),

Chroma [saturation, purity, strength, intensity] (intense vs. dull), and

Hue (e.g. the name of the colour family: red, yellow, green, cyan, blue, magenta).

The visual impact of "yellow" vs. "blue" hues in visual design depends on the relative lightness and saturation of the hues.

These confusions are partly historical, and arose in scientific uncertainty about colour perception that was not resolved until the late 19th century, when the artistic notions were already entrenched. They also arise from the attempt to describe the highly contextual and flexible behavior of color perception in terms of abstract color sensations that can be generated equivalently by any visual media.
