Can you attach your preferences file?

My initial guess would be around quote signs being copied incorrectly from browser.

Hey Connor,

There was an incorrect syntax, type="categorical" is invalid

i've modified it to type="regular"

use this attached .tps file to resolve ur issue.

Cheers,

Rahul

Yeah... you are welcome, community forum is a very useful place...

Hi,

Your example of the .tps file for a customised colour palette was very helpful. I copied your quote marks and it worked.

The Online Help article  http://onlinehelp.tableau.com/current/pro/desktop/en-us/help.htm#formatting_create_custom_colors.html?lang=en-us says: When you modify Preferences.tps to add colors, use the standard HTML format for the new colors (hexadecimal value #RRGGBB or Red Green Blue format).

I can get it working with hexadecimal value but not Red Green Blue format. Have you managed to do this?

I've attached my two .tps files. Preferences.tps works but Preferences RGB not working.tps just gives black.  I need to be able to use both formats because not all the brand colours are available to me in hexadecimal value.

Regards,

Helen

Hi Helen,

Tableau renders color palette using the hexadecimal color code which was stored in .tps file

RGB values wont work so they need to be converted to #hex before proceeding.

Have this site handy for conversion: RGB-to-Hex Color Converter

Eventually all possible RGB combinations will lead to 256 * 256 * 256 = 16,777,216 colors

and every RGB color combination can be converted to #hex format.

Thanks Rahul,

I've used a conversion tool long ago and forgotten all about it! Thanks so much for reminding me. I've got a full set of colours in my custom palette now.
