Power BI Report Server Branding Issue

Server Version: 1.20.8926.40580 (May 2024)

Issue:

A while back we investigated changing the branding on the server using the Multicolored example brand zip file seen here.  
After creating the new branding package and successfully deploying it we noticed that one element refused to change with the new branding colours ("Primary" and "PrimaryAlt") which shows as #117865 (dark green) instead of #e71f85 (pink)

"Primary" should adjust this green button to pink

Reverting the server back to default branding doesn't alter it either, as if the link between the two is broken. 

Once reverted back you can see the green remains.

All the elements in the json file were accounted for to make sure this colour wasn't in there.

Here's the JSON:

"name":"Multicolored example brand",
"version":"1.0",
"interface":{
"primary":"#e71f85",
"primaryAlt":"#ffffff",
"primaryAlt2":"#0080c9",
"primaryAlt3":"#009ad4",
"primaryAlt4":"#ffffff",
"primaryContrast":"#000000",

"secondary":"#0c499c",
"secondaryAlt":"#0c499c",
"secondaryAlt2":"#0080c9",
"secondaryAlt3":"#ffffff",
"secondaryContrast":"#ffffff",

"kpiNeutralContrast":"#ffffff",
"kpiNoneContrast":"#ffffff",

"itemTypeIconColor":"#ffffff",
"reportIconBackground":"#009ad4",
"excelIconBackground":"#009ad4",
"folderIconBackground":"#009ad4",
"datasetIconBackground":"#009ad4",
"otherIconBackground":"#0c499c"
}
}

 

Another poster had a similar issue which was fixed when they upgraded their version of report server to the January 2023 Release. Since our version is newer (May 2024) that hasn't resolved it.

Any ideas where to go next? 

Thanks in advance
Tim

SOLUTION: 

Added this additional code to the colors.json file.
