Color or colour is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra, and interference. For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelengths, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain.
Color blindness or color vision deficiency (CVD) is the decreased ability to see color or differences in color. The severity of color blindness ranges from mostly unnoticeable to full absence of color perception. Color blindness is usually an inherited problem or variation in the functionality of one or more of the three classes of cone cells in the retina, which mediate color vision. The most common form is caused by a genetic condition called congenital red–green color blindness, which affects up to 1 in 12 males (8%) and 1 in 200 females (0.5%). The condition is more prevalent in males, because the opsin genes responsible are located on the X chromosome. Rarer genetic conditions causing color blindness include congenital blue–yellow color blindness, blue cone monochromacy, and achromatopsia. Color blindness can also result from physical or chemical damage to the eye, the optic nerve, parts of the brain, or from medication toxicity. Color vision also naturally degrades in old age.
Electronic paper or intelligent paper, is a display device that reflects ambient light, mimicking the appearance of ordinary ink on paper – unlike conventional flat-panel displays which need additional energy to emit their own light. This may make them more comfortable to read, and provide a wider viewing angle than most light-emitting displays. The contrast ratio in electronic displays available as of 2008 approaches newspaper, and newly developed displays are slightly better. An ideal e-paper display can be read in direct sunlight without the image appearing to fade.
The Game Boy Color is an 8-bit handheld game console, manufactured by Nintendo, which was released in Japan on October 21, 1998, and to international markets that November. It is the successor to the Game Boy and part of its product line. Compared to the original, the Game Boy Color features a color TFT screen rather than monochrome, a processor that operates twice as fast, and four times as much memory. It retains backward compatibility with games initially developed for its predecessor. Reviewers considered these improvements insufficient to justify Nintendo releasing it as a separate product.
In computer graphics and digital photography, a raster graphic represents a two-dimensional picture as a rectangular matrix or grid of pixels, viewable via a computer display, paper, or other display medium. A raster image is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats.
The RGB color model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
Color management is the process of ensuring consistent and accurate colors across various devices, such as monitors, printers, and cameras. It involves the use of color profiles, which are standardized descriptions of how colors should be displayed or reproduced.
Onyx is the parallel-banded variety of chalcedony, a silicate mineral. Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands. Onyx has parallel bands, while agate has curved bands. The colors of its bands range from black to almost every color. Specimens of onyx commonly contain bands of black or white or both. Onyx, as a descriptive term, has also been applied to parallel-banded varieties of alabaster, marble, calcite, obsidian, and opal, and misleadingly to materials with contorted banding, such as "cave onyx" and "Mexican onyx".
In color reproduction and colorimetry, a gamut, or color gamut, is a convex set containing the colors that can be accurately represented, i.e. reproduced by an output device or measured by an input device. Devices with a larger gamut can represent more colors. Similarly, gamut may also refer to the colors within a defined color space, which is not linked to a specific device. A trichromatic gamut is often visualized as a color triangle. A less common usage defines gamut as the subset of colors contained within an image, scene or video.
An e-reader, also known as an e-book reader, is a portable electronic device that is designed primarily for the purpose of reading e-books and periodicals. E-readers have a similar form factor to a tablet; usually use electronic paper resulting in better screen readability, especially in bright sunlight; and have longer battery life when compared to a tablet. An e-reader's battery will typically last for multiple weeks. In contrast to an e-reader, a tablet has a screen capable of higher refresh rates which make them more suitable for interaction such as playing a video game or watching a video clip.
The iPod Nano is a discontinued portable media player designed and formerly marketed by Apple Inc. The first-generation model was introduced on September 7, 2005, as a replacement for the iPod Mini, using flash memory for storage. The iPod Nano went through several models, or generations, after its introduction. Apple discontinued the iPod Nano on July 27, 2017.

An e-reader, also called an e-book reader or e-book device, is a mobile electronic device that is designed primarily for the purpose of reading digital e-books and periodicals.
scRGB is a wide color gamut RGB color space created by Microsoft and HP that uses the same color primaries and white/black points as the sRGB color space but allows coordinates below zero and greater than one. The full range is −0.5 through just less than +7.5.
Amazon Kindle is a series of e-readers designed and marketed by Amazon. Amazon Kindle devices enable users to browse, buy, download, and read e-books, newspapers, magazines, Audible audiobooks, and other digital media via wireless networking to the Kindle Store. The hardware platform, which Amazon subsidiary Lab126 developed, began as a single device in 2007. Currently, it comprises a range of devices, including e-readers with E Ink electronic paper displays and Kindle applications on all major computing platforms. All Kindle devices integrate with Windows and macOS file systems and Kindle Store content and, as of March 2018, the store had over six million e-books available in the United States.
Onyx Boox is a brand of e-book reader produced by Onyx International Inc, based in China. Like most e-book readers, the Boox uses electronic paper technology.
Shades of black, or off-black colors, are colors that differ only slightly from pure black. These colors have a low lightness. From a photometric point of view, a color which differs slightly from black always has low relative luminance. Colors often considered "shades of black" include onyx, black olive, charcoal, and jet.
The Nokia 7 Plus is a Nokia-branded upper-mid-range smartphone running the Android operating system. It was announced on 25 February 2018, along with four other Nokia-branded phones.
The iMac with Apple silicon is a line of all-in-one desktop Macs made by Apple Inc. since 2021. The first major redesign of the iMac line since 2012, the case and internals were redesigned to use Apple's custom processors, starting with the M1 system on a chip. The Apple silicon iMac features a 24-inch screen in a thin aluminum enclosure, elevated off the resting surface by a foot, and comes in seven colors.
The Samsung Galaxy Z Flip 3 is a foldable smartphone that is part of the Samsung Galaxy Z series. It was revealed by Samsung Electronics on August 11, 2021 at the Samsung Unpacked event alongside the Z Fold 3. It is the successor to the Samsung Galaxy Z Flip, although it is branded as the Flip 3 to align with the branding of the accompanying Fold model.
