The Chubb illusion is similar to another visual illusion, the contrast effect.The contrast effect is an illusion in which the perceived brightness or luminance of an identical central visual target form on a larger uniform background varies to the test subject depending on the ratio of the central form's luminance to that of its background.

Weber contrast is commonly used in cases where small features are present on a large uniform background, i.e., where the average luminance is approximately equal to the background luminance. A photograph of a leaf with several colors—the bottom image has an 11% saturation boost and around 10% increase in contrast.
Neumorphism is a form of minimalism characterized by a soft and light look, often using pastel colors with low contrast. Elements are usually the same color as the background, and are only distinguished by shadows and highlights surrounding the element. This gives the elements the appearance that they are "protruding" from the background, or ...
While the background has black and white stripes, the contrast changes from one line to the next. [1] Both black and white lines have different patterns in contrast, for the dark object (blue bus), high contrast object against white lines and low contrast objects against black lines.
The basic intent of the contrast enhancement technique is to adjust the local contrast in the image so as to bring out the clear regions or objects in the image . Low-contrast images often result from poor or non-uniform lighting conditions, a limited dynamic range of the imaging sensor, or improper settings of the lens aperture.
Chiaroscuro is used in cinematography for extreme low key and high-contrast lighting to create distinct areas of light and darkness in films, especially in black and white films. Classic examples are The Cabinet of Dr. Caligari (1920), Nosferatu (1922), Metropolis (1927) The Hunchback of Notre Dame (1939), The Devil and Daniel Webster (1941 ...
Bright-field microscopes have low apparent optical resolution due to the blur of out-of-focus material; Bright-field microscopes typically produce low contrast with most biological samples, as few absorb light to a great extent. Samples that are naturally colorless and transparent cannot be seen well, e.g. many types of mammalian cells.
He found the default white-on-black schemes of most applications to be too high in contrast. Even for low-contrast schemes, some colors were more prominent than others. This was an issue for programming, as code editors use syntax highlighting, where color is used to indicate the different parts of the code. [4]
