The CQvis MultiGradient Palette ToolScreenshot
In addition to gradient shades, tints, and grayscale, random colors or file bitmap colors may be added to the palette strips to be used as a basis for gradients to be displayed, selected from, modified, or concatenated. Palettes can be saved to or loaded from files containing bitmaps, UInt32 arrays, or text/html strings of hex digits. Requires .NET Framework 3.5, but does not need to be installed, or uninstalled for removal from your system.
