Violetini

Could you clarify what Violetini refers to? It could denote different things in various contexts, such as a biological taxon, a pigment or color term, a surname or brand, or a fictional concept. If you specify the intended domain (for example, biology, chemistry, culture, or fiction) and any particular scope or sources you want included, I can generate a concise, neutral, wiki-style article under 300 words.
