Teroid Color Browser is a .NET control with an extensive set of properties allowing different palettes to be presented to users in a variety of ways, such as the samples in the screenshots.

The Style property can be set to display the selected palette in a list box, a dropdown combo box or a set of buttons in either a square or a horizontal or vertical strip. The Palette property provides a choice of 16 colors, web colors (141 colors) or system colors, and an event is raised whenever the user makes a selection.
