I'll update the color theme to use red and grey throughout the application. Let me modify the Tailwind configuration and update the components to use the new color scheme.

I've updated the entire application to use a red and grey color theme! Here are the key changes I made:

Color Theme Updates:

Primary Colors:

• Red: Used for primary actions, icons, and highlights
• Grey: Used for secondary elements, text, and neutral components

Specific Changes:

1. Tailwind Configuration: Updated the color palette to use red as primary and grey as secondary colors
2. Icons & Branding: Changed all Dumbbell icons and brand elements to red
3. Buttons: Primary buttons now use red background with white text
4. Navigation: Active links are red, inactive links are grey
5. Progress Elements: Progress bars, achievement badges, and success states use red
6. Cards & Highlights: Selected states and important elements use red backgrounds
7. Authentication: Login/register forms use the new red theme

Color Hierarchy:

• Red-600: Primary buttons, active states, brand elements
• Red-100: Light backgrounds, subtle highlights
• Grey-500/600: Secondary text, inactive elements
• Grey-100: Light backgrounds, cards
• Grey-700: Dark text, advanced difficulty badges

The new theme gives your fitness app a bold, energetic feel with the red color while maintaining excellent readability and professionalism with the grey accents. The red conveys strength and motivation, perfect for a fitness tracking application!
