Cosmos Announce Image

Creating the announcement banner for the COSMOS home page

  1. Download and install The GIMP for your platform
  2. Start the GIMP
  3. Open a previous banner image. All previous ones are in CVS, or you can just save the current one off the COSMOS home page.
  4. From the Edit menu, choose Colors > Colorize
  5. Change the Hue, Saturation, and Lightness values to your liking. Generally a Saturation of 100 and a medium Lightness (22?) works well. The Hue is the thing that gives you the different colors. Click OK.
  6. File > Save As... a new name

You're all done!
