Question

Palettes are used to monitor and modify text and graphics in a publications

Answer 1

Answer:

As of 2019, the most common image colorspace in computing is the RGB color model with 8 bits per pixel color depth. Using this technique, 8 bits per pixel are used to describe the luminance level in each of the RGB channels, therefore 24 bits of storage are necessary to fully describe the color of each pixel. The objective of the usage of palettes is to lower this storage requirement by reducing the set of possible colors that are to be handled at once (often using adaptive methods), assigning each possible color is assigned an index, which allows each color to be referenced using less information than needed to fully describe the color. A common example is the 256-color palette commonly used in the GIF file format, in which 256 colors to be used to represent an image are selected from the whole 24 bpp color space, each being assigned an 8 bit index. This way, while the system can potentially reproduce any color in the RGB color space (as long as the 256 color restriction allows), the storage requirement per pixel is lowered from 24 to 8 bits per pixel.

Answer 2

True, palettes are used to monitor and modify text and graphics in a publication.

• A palette, also known as a colour lookup table (CLUT), is a correspondence table in computer graphics that assigns an index to selected colours from a colour space's colour reproduction spectrum so that they can be referenced.
• Palettes are used to reduce storage requirements by decreasing the number of possible colours that must be processed at once and assigning each conceivable colour an index, which allows each colour to be accessed with less information than is required to completely describe the colour.
