Let's break down the words:
* niramulla: This is a combination of "niram" (color) and "ulla" (having/possessing). It essentially means "having no color" or "colorless."
* ormakal: This is the plural form of "orma," meaning "memory."
Therefore, "niramulla ormakal" signifies memories that lack vibrancy, intensity, or emotional depth, perhaps suggesting faded or forgotten moments.
