Need help : choosing a default color palette for charts
As you may know, a new chart module is being developped. One of the more visible issue with chart are its colors. You can see Issue 7019. Hence, help is needed to choose colors which would look better. That's an interresting task for anyone wanting to help with OOo as no-programming knowledge is required. Before you start working, here are the requirements your palette has to fulfill :
- There are 12 colors needed.
- They should be suiteable for thin lines as well as filled areas.
- They should be distinguishable on black and white printers as well.
- They should be suitable for 2D and 3D charts.
Once you found something, you can post the references of the colors on the issue. If you have any question, you can come to the IRC channel on freenode : #chart2.openoffice.org.
Tips related to colors :

- for changing default colors of a newly created chart : Tools > Option... > Chart > Default Colors

This seems to be too ambitious : 12 really distinguishable gray levels for B&W printing ? It would be best if the first-used colors were really distinguishable, but I don't believe you'll get 12.
What about color-blind users ?

"Everyone knows that this is difficult. MS solved the problem by ignoring B&W and using different (very ugly) colors for lines."
That's true that finding those 12 colors is difficult (not to say nearly impossible), but if no-one tries, there is no chance to find ;-)
So, let's just try. Maybe we can then select only 6 or 8 really distinguishable colors.

"For the black and white printing I think it would be sufficient when the new colors are at least the same distinguishable as the old ones"
