Netscape Color Cube

The Netscape browser uses these 216 colors in its palette. By using these colors on your web pages, not only the viewer will see your images exactly as you intended, but also the size of the graphic will be reduced.

1. Save the image above to your hard disk.
2. Open the image in Photoshop.
3. Change mode to indexed color using "exact palette" and color depth of 8 bits/pixel (Image/mode/indexed color, the image may already be in this mode).
4. Open the color table (Image/mode/color table).
5. Save the palette as "colorcube.tbl" onto your hard disk.
6. Cancel out of the Color Table dialog box.
7. Go to Swatches in your colors window.
8. Click on the right arrow to pop up a submenu, and choose "Load Swatches."
9. Search your hard disk to find "colorcube.tbl," and open that color table.
10. Quit and restart Photoshop to get the changes effect. You may now use it to choose colors for creating and manipulating images optimized for WEB graphics.
11. The color arrangement of the cube is confusing. If you find a better one, please let me know :-)
