​
Icon Colors Configuration File

Go to /constants/colors.ts: 
export const colors = {
  icons: {
    base: {
      light: '#000000',
      dark: '#FFFFFF',
    },
    primary: {
      light: '#FF6B35',
      dark: '#FF6B35',
    },
    secondary: {
      light: '#374151',
      dark: '#374151',
    },
    success: {
      light: '#10B981',
      dark: '#10B981',
    },
    error: {
      light: '#EF4444',
      dark: '#EF4444',
    },
    warning: {

      dark: '#F59E0B',
    },
    info: {
      light: '#3B82F6',
      dark: '#3B82F6',
    },
    muted: {
      light: '#9CA3AF',
      dark: '#9CA3AF',
    },
  }
}

Icon Colors Hook

Create /hooks/useIconColors.ts: 
import { useTheme } from '@/context/ThemeContext';
import { colors } from '@/constants/colors';
 
export const useIconColors = () => {
  const { isDark } = useTheme();
 
  return {
    base: colors.icons.base[isDark ? 'dark' : 'light'],
    primary: colors.icons.primary[isDark ? 'dark' : 'light'],
    secondary: colors.icons.secondary[isDark ? 'dark' : 'light'],
    success: colors.icons.success[isDark ? 'dark' : 'light'],
    error: colors.icons.error[isDark ? 'dark' : 'light'],
    warning: colors.icons.warning[isDark ? 'dark' : 'light'],
    info: colors.icons.info[isDark ? 'dark' : 'light'],
    muted: colors.icons.muted[isDark ? 'dark' : 'light'],
  };
};
