The seven colors of the rainbow (red, orange, yellow, green, blue, indigo, and violet) are typically referred to as ROY G. BIV in English. These colors, and their names, can vary slightly in other languages. Here's how they translate in a few common languages:

Red: Rot, Orange: Orange, Yellow: Gelb, Green: Grün, Blue: Blau, Indigo: Indigo, and Violet: Violett.

Red: Rosso, Orange: Arancione, Yellow: Giallo, Green: Verde, Blue: Blu, Indigo: Indaco, and Violet: Viola.

Note: Some languages may have variations in how they express certain colors, or may not have a direct one-to-one translation for "indigo" or "violet". Additionally, some languages might have different nuances in how they perceive or categorize colors, as highlighted in discussions on color perception and language.
