If one does much work with colors it is quite convenient to have the ColorSchemes palette up and in a convenient place. However, I find that this palette has some undesirable properties. It does not remember either its position or state between Mathematica sessions such as the BasicMathInput or SpecialCharacters palettes do. I went to the Wolfram files and made a copy of the ColorSchemes.nb and saved it in one of my own folders - just in case of problems. Then I opened Mathematica, brought up the ColorSchemes palette and used the Option Inspector on it to change: Notebook Options File Options Editable changed to True Saveable changed to True ClosingAutoSave changed to True This worked and the palette now remembers both its position and state and appears to function properly. However, I wondered if there was a reason that WRI set those options to False? Another feature of the ColorSchemes palette that I dislike is the operation of the slider bars. They are hardly adequate for scrolling through the colors and schemes, being too sensitive when the list is long. They would be much better if a "LeftStepButton" and "RightStepButton" (or in this case up and down) could be added to the controls, or if once one had selected a color or scheme, the up/down arrow keys could be used to scroll through the list. For those who are used to using the old named colors in the Graphics`Colors` package and are now dismayed at the great amount of typing needed in the new scheme the following routine might be useful: color[] := ColorData["Legacy", "Range"] color[c_] := ColorData["Legacy"][SymbolName[c]] color[] color@RawUmber In general, the additional typing is worth the richness of the new color schemes. -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/
