Editing stylesheets - otfried/ipe-wiki GitHub Wiki

There are two ways to specify colours, line widths, fill styles, and so on in Ipe. You can either use one of the symbol values provided, such as ultrafat, or darkgreen; or you can specify exact values like 2.0, or #ff00ee. Symbolic values have the advantage that you can change all of the values at once. For example if you are creating a document about interest rates, you could create the colours rpi_colour and cpi_colour, and then at a later date you can change the colours of all the RPI lines at once.

Ipe comes with a limited set of default symbolic values. These are defined in Ipe stylesheets.
