The dvipsnames option predeclares all the names in the colour prologue of dvips . The dvips option automatically implies dvipsnames , unless one explicitly overrules this choice by specifying the nodvipsnames option. Conversely, if with another driver, eg. textures , one wants to use these names then one has to specify the dvipsnames option. Finally, the usenames option makes all names of the named colour model available, as described in section . The colours black , white , red , green , blue , cyan , magenta , yellow should be predefined by any driver.

Coloured box backgrounds Two commands similar to Lcsframebox produce boxes with the backgrounds shaded with a given colour. The examples below show how these commands are used. A few final examples show you how the exact form of the box can be controlled.
