Final answer:
The question seems to be grounded in the interpretation of two paintings, 'Nightlife' and 'Cocktails,' which portray a speakeasy scene indicative of the Prohibition era, rather than providing information about actual seasonal cocktails or special nights.
Step-by-step explanation:
The question appears to be related to an analysis of two paintings Nightlife and Cocktails by an artist referred to as Dr. Zaro. The description of these scenes highlights the vibrant atmosphere of a speakeasy during the era of Prohibition when alcohol was illegal.
The paintings themselves do not directly provide information about specific seasonal cocktails or the nights on which they might be on special; rather, they offer an artistic representation of the social dynamics and diverse clientele within such an establishment. The warm palette and diverse depictions of the women and waiter suggest a celebration of color and diversity in a time of clandestine conviviality.
