Color model determines the color model used to display and print the image.
- RGB (Red, Green, Blue): a very large percentage of the visible spectrum can be represented by mixing red, green and blue (Red, Green and Blue) are given bright colors in various proportions and intensity. By mixing red, green and blue will create the color white. 0Ieh therefore also called RGB models with additive colors (color mix).
- CMYK (Cyan, Magenta, Yellow, Black): CMYK is based on the quality of the light absorption of ink printed on paper. Whiskers, white light causes the ink to be invisibility, a portion of the spectrum is absorbed, and the other K at CWK reflected back toward the eye
- Bitmap Mode: This mode uses one of two color values (black or white) to represents the pixel into the image. Bitmap Image in a mode called the Bitmapped 1-bit because the image has a bit depth of as much as 1.
- Grayscale Mode: This mode uses more than 256 shades of gray. Each pixel of an image to grayscale mode has a value of brightness (brightness) with a range of 0 (Black) to 255 (white). Grayscale values can also be applied as a percentage with 0% were white, and 100% is black.
- Duotone Mode: This mode us es 256 colors. At the time of converting to indexed color, Photoshop will create a CWT (Color Lockup Table) which stores and indexes colors in an image. If there is a color in the original image does not appear on table, the program will select the color closest to the color, or simulate colors using the colors that have been available.
- Multichannel Mode: This mode uses 256 levels, from the gray in each channel. Image uing Multichannel mode is very useful for specialty printing.
