Color name by R/G/B HEX or 256 colors

Is there somewhere one can find a defined 265 color hex% for basic 256 color names?The reason I want to do this is for my own identification of land coverage/land use, water types, and highway types. I want to use TerraScene to develop a map in solid colors to definme each land type, water type, and transportation types, then use my color selections to set FS2K2 textures from the colors I have set. As it is possable to set solid colors in R/G/B% for each type of texture I can make a list of each as I develope each map and LONG/LAT extents. Then I can use Ground2K from what I read and select each of my maps defined color for each texture for FS2K2. There was talk quite a while back that tools simular to TeraScene were in the works but to date no mention any progress in the project. Any help or suggestions on this would be greatly [email protected];
