I am using the siemens logo svg from brandville (sie-logo-white-rgb.svg) How do I make the color change as per the theme toggles?
I guess it is about changing the color of the logo in the app header?
Using the logo from brandville is usually not necessary. You need the Siemens brand theme from https://code.siemens.com/siemens-ix/ix-brand-theme. This theme contains the Siemens brand colors and the Siemens logo. Please also see here: Themes | Siemens Industrial Experience
Just for info: This additional step is necessary since iX is Open Source but the usage of the Siemens brand theme is only permitted for Siemens applications.
