MUI primary theme color changing in production AWS Amplify

I am creating a nextjs 13 app router project using material UI. i have designed the theme using createTheme but the primary color sort of dulls down on its own when uploading on AWS AMPLIFY. the changes look fine locally but not on cloud.

Dependencies i am using in the current project:
