Score the chicken by cutting 2 diagonal slits to soak in the marinade. Make the chili paste with the 2 tbsp chili powder, half the salt, and lime juice. Mix into the chicken and let sit for 30 minutes. Make the yogurt marinade by adding the rest of the ingredients with a few drops of red food coloring to the desired color if using. Let marinate for 3 up to 24 hours.
