think-cell uses Microsoft PowerPoint's theme colors for many chart elements (e.g., axes, text, arrows, etc.). These colors are taken from the theme colors of your presentation file. If the defaults are designed correctly, think-cell will follow seamlessly when you switch the color scheme.
In general, it is advisable to store these defaults in a PowerPoint template file (*.potx) and to derive all new presentations from this template file. Please refer to the PowerPoint help for information on how to do this.
If you want to change the default font used for think-cell please refer to our knowledge base article: KB0100: How can I change the font color?
The colors think-cell uses in charts are Accent 1 - Accent 6. The colors think-cell uses for text and chart decorations are Text/Background Dark 1 or Text/Background Light 1.

With a think-cell style file you can define colors which differ from PowerPoint's template colors. Style files also let you define your own menus and work on a per-template or per-file basis. For details, please refer to the user manual at Appendix C: Customizing think-cell.
