I have changed the background theme successfully. But i am facing problem in all Charts, while setting colors in chat. below i have shared my screen shorts.
1. If i select single color working fine.
2. If i select By dimension all lines are showing black color.
3. If i select By expression it shows error.
How did you managed to change the theme?
I know we can only change the theme to hivis but your pics looks bit different.
The theme.json resides at C:\Users\...\AppData\Local\Programs\Qlik\Sense\Client\themes\highvis\theme.json
I haven't tried it, but I think modification of css isn't enough to get the desired output.
The content of json file is straightforward, you can simply recognise each block meaning.
