How to modify and save default system color palette in dashboard CA11

[EE]

Hello Everyone,

I have an R&D on Dashboard changing the default system color palette in Dashboard in Cognos Analytics11.

Requirement

Need to create/ modify a default system color palette. When a dashboard report is created it should be created with our default custom color palette. No end-user has to select the color palette. It should be selected by default.

I have changed in Cognos Analytics Report tool and Cognos 10 Report Studio in both environments. Now, I want to change the Dashboard too.

I've searched for the locations of the dashboard scripts to find the related information/ script.

I found the dashboard-analytics folder in two different locations. One folder contains CSS and images SVG files and the other contains js and JSON files, I found PropertiesCreator.js and PropertiesCreator.j.map files under the below location.
Install-Location\webcontent\bi\js\dashboard-analytics\visualizations\properties

I found ColorPropertiesCreator.js and ColorPropertiesCreator.j.map files under the below location.
Install-Location\webcontent\bi\js\dashboard-analytics\visualizations\vipr\properties

But none of these files are related to the system color palette in the dashboard.
Below is the attachment I've added.

So Please, If anyone had gone through this kind of R&D or if anyone knows about this then help me out to do it.

Thanks in advance :) :) :)
