How can I dye noodles to create colorful and vibrant dishes?

To dye noodles for colorful dishes, first cook the noodles until al dente. Then, separate the noodles into different bowls and add food coloring or natural dyes like beet juice or turmeric. Mix well until the noodles are evenly colored. Let them sit for a few minutes to absorb the color, then rinse with cold water to set the dye. Finally, use the colorful noodles in your dishes for a vibrant presentation.
