• About eight percent of all men have some sort of color deficiency, however women only have about half of a percent.
• There are three cones within the eye called the following, the L-cone, M-cone and S-cone, all which acknowledge red wavelengths, green wavelengths and blue wavelengths.
• Any color deficiencies occur in the L-cones or M-cones.
• If there is low light, cones do not detect them. However this is when the rods in our eyes kick in and since they do not determine different wavelengths it creates a blue-gray vision that is called nighttime.
• Color blindness affects more males than females.

• Simultaneous contrast affects our insight of black-and-white images, such as a midgray object will seem to be darker a background that is white rather than a background that is black.
• The effects on combinations of black and white with other colors is slightly different, such as red being brighter on a black background as well as seem warmer.
• Through various color combinations it can produce an intensified color experience, giving vibrant or luminous colors or cancel out.
• With two different primaries alternated with horizontal and vertical black stripes causes someone to see false colors in black-and-white stripes of the same emphasis.
• Our visual system tends to expect the complement of whatever color we may view. If a complement is present, the combination looks vibrant. However if it is absent, we create it ourselves.

• Itten did not limit himself to examining color scientifically; instead he went beyond and tempered with light waves and reflections or in other words, color relationships and visual effects.
•  With the belief that color harmony is entirely subject and with the availability to experiment, Itten stated that each person ultimately creates his or her own palette.
• Itten produced a color stare that expands beyond the basic color wheel, expressing numerous variations of lightness.
•  It was soon discovered through the tricks with color and geometry, op art grew heavily on the field of perceptual psychology.
• Goethe pursued the way human nature makes us respond to color, which within color psychology, is how personal color preferences might relate to individual character.

Color can be looked at entirely different ways due to studying color versus actually using color within a piece of artwork. However, it was Network that took color spectrum and produced it into a circle. Furthermore, like most color wheel pertain to pure hues, with a few changes within the saturation or lightness. Which lead there to be several color wheels and multiple alterations. Most color wheels pertain to pure hues, with a few changes within the saturation or lightness.

I found it interesting as to how far the idea of color relationships going back as far as Aristotle, which I would have never of guessed. Let alone the numerous various of color wheels that can be found by just Googling “color wheel”.
