The optical refinements of the columns were such things like the fact they bulged slightly in the middle and the corner columns were slightly bigger and inclined inwards making everything look straight when looking at it.
As for the temple, the floors tend to be more built up in the middle so it doesn't look like it sags.
Optical illusions were first used by the Greeks. They built their temples so that the roof was slanted. This gave the illusion that the temple was actually standing straight. They also made the columns bulge so that from a distance they would look perfectly proportioned. In the course of history, people have encountered illusions in many ways. Many of these illusions appear in very common, everyday experiences.
What’s the answer
The question is too vague to be meaninful. Some optical illusions INVOLVE color, so for them I suppose the answer would be yes. Others don't, and the answer there might be either no or yes; it's difficult to say without more details.
Wall art décor are large art pieces that are hung on the wall and can include things such as tapestries, framed and unframed paintings and pictures, sculptures and Trompe L'oeil. Trompe L'oeil are optical illusions where two dimensional objects appear three dimensional to the eye.
An optical illusion that is caused by atmospheric conditions in which nonexistent bodies of water are seen is commonly referred to as a mirage. This is most common in extremely hot climates, and although the most common mirage is of bodies of water, there are other illusions that may appear to a person, as well.
Humans appear to levitate through optical illusions.

In many cases, such as in the Parthenon the rows of columns would appear to be concave (an optical illusion) because of the fluting, or the lines, that run from the top to bottom of the columns. The Greeks knew this however, so they figued out how to build up the middle of the pillars to make them appear strait.
Optical illusions are pictures that use color, patterns, and light to trick the eyes and brain. When viewing an optical illusion, what the eyes see is interpreted by the brain, but the brain's interpretation does not match the true image. In fact, the brain sees something that is not really there. Optical illusions are fun to look at, but they also help scientists to learn how the brain works. Many optical illusions were created just to study how the brain processes visual information. There are three basic types of optical illusions: literal, physiological, and cognitive. Literal optical illusions form images that are unlike the objects that create them. The best way to understand a literal illusion is to look at one. An example of a literal illusion is the painting Bakery by Octavio Ocampo. In this painting, a woman sits in front of shelves full of bread in a bakery. However, the way the bread is arranged appears to form skulls. Another famous example of a literal optical illusion is the painting All Is Vanityby Charles Allan Gilbert in which a woman sitting at a vanity table looks like a skull when viewed from further away. Physiological illusions happen when excessive stimuli such as brightness, color, movement, or tilt, for example, cause the eyes or brain to see something that is not there. These illusions can also occur when stimuli compete. The Hermann grid illusion is a famous example of a physiological optical illusion. The Hermann grid is a white grid on a black background. When looking at it there appear to be gray dots at the intersections of the white lines, although in reality there are no gray dots. This is due to a physiological phenomenon called lateral inhibition which is when light and dark photoreceptors compete with each other and one part wants to become active and the other does not. This causes a perceptual illusion of gray dots on the grid. Cognitive illusions occur when the eye and brain make unintentional inferences. There are four types of cognitive illusions: ambiguous, distorting, paradox, and fictional. Ambiguous illusions offer two interpretations of a picture or object, but both can't be seen at the same time. A famous example of an ambiguous illusion is the Rubin vase, which either looks like a white vase or two face silhouettes facing each other. Distortions in length, size, and curves appear to be present in distorting illusions. A famous example of this type of illusion is the arrow illusion, otherwise known as the Mueller-Lyer illusion. In this illusion there are two lines that are the same size but one has the ends pointing in and one has ends pointing out; most people say that the line with the ends pointing in is longer. Paradox illusions are objects that are impossible in real life but look real in drawings, such as the Penrose stairs, which seem to go on forever without getting any higher. This illusion is due to the faulty belief that adjacent edges have to meet. The Penrose triangle is another example of a paradox illusion. Fictional illusions are only seen by a single person; they are actually hallucinations. They can be induced by alcohol or drugs, or by health conditions such as schizophrenia. Examples of fictional illusions are seeing double of one object or seeing something move when it really doesn't. Literal, physiological, and cognitive illusions all deceive the eyes and brain. People have been fascinated by optical illusions throughout history, and continue to be fascinated by them today. Paintings, books, and drawings of optical illusions have become famous because they are fun to look at; however, they also help scientists to discover how the brain works. Fun and science often go hand in hand.

Optical illusions involving the moon can make it appear larger or closer than it actually is in the night sky. This can distort our perception of its size and position, leading us to believe it is closer to the horizon when it is actually higher up.

To create optical illusions by bending light, you can use lenses or mirrors to change the path of light rays. By manipulating the way light travels, you can distort images, create mirages, or make objects appear larger or smaller than they actually are. This bending of light can trick the brain into perceiving something that is not actually there.
False. Resolution refers to the amount of detail that can be seen in an image. When objects appear larger than they really are, it is usually due to optical illusions or perspective.
Rainbows don't have a specific distance since they are optical illusions that appear when sunlight is refracted and reflected by water droplets in the air. However, they typically appear relatively close to the observer, usually within a few kilometers.
No, resolution refers to the clarity and level of detail in an image or display. When objects appear larger than they really are, it may be due to optical illusions, perspective, or other factors.
