Hello -
i have the challenge to modify some colors to match our CI guidelines - using tables and matrix in Power BI i need to change the background color of the column headers. I tried the following JSON input:
{
"name":"test design",
"dataColors": [ "#004459", "#54B7C6", "#AB0953", "#BAC405", "#667C72", "#633A11", "#006686", "#AB0953" ],
"background":"#F5F8FC",
"foreground":"#003366",
"tableAccent":"#214F80",
"visualStyles": {
"tableEx": {
"*": {
"columnHeaders": [{
"backColor":"#004459",
"fontColor":"#ffffff",
"wordWrap":false,
"fontSize":9,
"urlIcon":true
}],
"values": [{
"wordWrap":false,
"fontSize":8,
"urlIcon":true
}]
}
}
}
}Syntax seems to be ok - font size and other parameters changing - "backColor" is not working at all. Any thoughts what i'm doing wrong or is it a bug?
Many thanks and best regards,
Stephan
Solved! Go to Solution.
I was able to use this to change the background color of my table headers:
{"name":"My Theme","visualStyles":{"*":{"*":{"*":[{"color":{"solid":{}}}]}},"tableEx":{"*":{"columnHeaders":[{"backColor":{"solid":{"color":"#123456"}}}]}}}}

No problem, I recommend @Mike_Carlo's https://powerbi.tips for this. Use the Advanced Theme Generator to stitch together the right syntax!
