Multichannel A "super-mode" that allows for spot colors to be used.
Channels are not directly accessible, but are manipulated by proxy through Curves. Special color modes Duotone A printing-oriented mode that, contrary to its name, allows for monotones, duotones, tritones, and quadtones. Although no longer present as color modes in current versions, HSB remains as an option in the Color Picker, Info, and Color Sampler palettes the Hue/Saturation adjustment and the Luminosity blending mode is based on HSL. The two differ in how the second and third parameters ( saturation and brightness or lightness) interact. HSB and HSL (Hue-Saturation-Brightness/Lightness) Two color modes based on cylindrical coordinates. Lab Intended to approximate human vision, and allows for certain edits that are useful in photo and video. CMYK (Cyan-Magenta-Yellow-Black) The next most common mode, it describes how colors will be composited by common printing processes. RGB (Red-Green-Blue) The most common color mode, which most closely resembles the sRGB profile that is standard for the majority of monitors and best describes how they generate color. The act of dividing each color into the different channels is called separation, and the act of combining them is called compositing-these are handled differently by each mode. Full-color modes Ī minimum of three channels is needed to represent the majority of colors visible to humans. Indexed color mode is not considered to have a channel, but is still useful in certain applications. Indexed An 8-bit mode that translates each of the 255 possible color values into an RGB triad. These modes differ in how many channels are used to represent a color, and how deep each channel is.īasic color modes Grayscale The most basic mode, consisting of a single channel that maps values to grays, from black to white. Version 2.5 only offered four modes: RGB, Indexed, Grayscale, and "Bitmap".Ĭolor modes were given their own menu, but were incorporated into the Image menu starting with version 4.0.Įvery image has a color mode. At some point, HSB and HSL modes were removed, although remnants of both remain as described below. Lab is the only mode not present since the beginning, and was added in 3.0. Color modes have been present in all versions of Photoshop.
