The Theme Lab, accessed with the New Theme button, lets you design the appearance of your maps. Start with a name for the theme.
Next, design your theme: the colors of the celestial bodies, the labels (font and colors), the constelation lines, and the grid.
The preview is a portion of a generic map created with your theme. The background is not part of the design (all the maps have transparent backgrounds), but it helps with visualization.
The proof is a watermark-free full size map, made according to your theme. It will allow you to make sample products and take photos without spending maps.
We SAVE the design to go back to the Map Lab, the map creation tool.
