Color scheme mismatch in notifications bar

Hi FC Team,

Need help with this color customization issue. I have created a custom color scheme for both dark and light modes. It works almost fine throughout the portal pages.

However, when I open the notifications bar, the background, notification icon, and the reaction icon show standard colors (black and red), which breaks the branding consistency.
Kindly fix this, and in the meantime, I'd appreciate it if you could help me with some custom CSS code snippet to fix this.
Thank you! <3
