# Color Modes (Color Picker) The NPS Color Picker can restrict the selectable colors to various color modes. This will prevent you from selecting a color value that does not fit. Most color selectors will likewise restrict their available choices to fit within the mode, but if this is not possible, a warning will be displayed and you can click it to update the dialog to the nearest valid color. The following modes are available (depending on the version of NPS Image Editor): ## True Color The default mode that allows all possible colors to be selected with no restriction. This allows 8 bits per channel (red, green, blue, alpha) and is elsewhere known as "24 bit" (when referring to R/G/B channels only) or "32 bit" (when including the alpha channel). ## High Color Restricts colors to 16-bit High Color mode. 5 bits are used for red and blue, and 6 bits are used for green. In Windows XP this is known as "Medium" color quality. Alpha is not restricted. ## Web Safe Restricts colors to the palette oi 216 "web safe" colors to maximize the chances of accurate color display on palette-limited (256 Colors) devices. ## Named Colors Restricts colors to the set of named colors (excluding system colors). This can also be achieved by using the Named Color format. ## Indexed Color Restricts colors to a specific palette. This mode is automatically selected when working with images in Indexed or Palette mode. You can also manually load a palette into the color picker using the Load Palette item. ## Grayscale Restricts colors to only shades of gray. ## Monochrome Restricts colors to only black and white.
