Shall I change the rendering of "cyan" and "magenta" > to the light colors too? Personally, I would make them consistent from this day forward, so I would say "yes" make MathML the same as Calc. I just found this reference area for color codes/names-- http://www.rapidtables.com/web/color/cyan-color.htm cyan = aqua in rgb http://www.rapidtables.com/web/color/purple-color.htm same for magenta = fuchsia Others may have a different opinion though. <orcnote> I've lost track, here, of what is recorded in the ODF file as a color choice (in MathML and in other places where there are color choices) and what is presented to the user as the name for the color (also on any drop-down from a sample of the color in a color-picker). Another place to figure out what is going on is the colors that were implemented beyond the 16 standard RGB names in HTML/XHTML. In that case, cyan is the same as cyan1 (and aqua) and magenta is the same as fuschia - that is, they are the brightest forms of the colors. Another way of looking at it: cyan/aqua is the complement of red, magenta/fuschia is the complement of green. </orcnote> > > Kind regards > Regina > > > > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@openoffice.apache.org > For additional commands, e-mail: dev-h...@openoffice.apache.org > -- ------------------------------------------------------------------------- MzK "One must still have chaos in oneself to be able to give birth to a dancing star." -- Friedrich Nietzsche --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@openoffice.apache.org For additional commands, e-mail: dev-h...@openoffice.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@openoffice.apache.org For additional commands, e-mail: dev-h...@openoffice.apache.org
