When it arises from joy the color is sometimes red, and but since this is not universal, examples of turning red from joy are not given.
Purport
If the color change takes place due to excessive jubilation, the hue turns red. Because such a change of color is so rare, Śrīla Rūpa Gosvāmī does not further discuss this point.
