This is technically a duplicate but I only found one post about my problem and its over 2 years old with no answer so I decided it would be okay to ask the question again. Other Post
I use React-Native and UI-Kitten and wanted to use Runtime Theming in order to switch between dark and light theme
Before I used Runtime theming I followed the Branding guide and used Eva Colors to generate the JSON File which worked completly fine (https://colors.eva.design/) until I used Runtime Theming which for whatever reason seems to override my theme-colors.
I have not made any changes from the guide-code so if you want to see how my code looks you can read these two short guides. Branding Runtime Theming
