Metaphors are basically comparing something that isn't literal. Google gives the example of "My mother is the black sheep of this family" but your mom isn't an actual black sheep. So a metaphor on red could be "red as bright as the moon in night" Even though red is color, and not a moon.
Red is the color of beauty itself, so lavish and pretty.

Red tastes like a thousand cakes. My mom's sweetest cookies rival the warmth.
Red feels smooth and delicate, just like velvet itself.
The beauty of red mimics a rose. Serene and fresh. The smell like a meadow, pure and clean
